People of Reddit who got rich by investing Bitcoin before 2017 boom, How did you find it out?

I am a newbie trader and I would love to hear some refreshing stories about bitcoin :)
submitted by UnderratedGrape to Bitcoin [link] [comments]

I had like 3 friends ask me how to build a PC in the past week so I made this to help them.

(Reddit Edit: Help my improve the document with productive constructive comments on what I got wrong or messed up! Im only human lol
Also a lot of this is supposed to be kinda humorous. I didn't think I had to say that but, hey, its the internet.
I appreciate the positive and productive comments! )
Beginners basic guide to building your own PC as of early 2018
(EDIT: Sorry for being a MSI/Corsair Fanboy)
Heres a collection of thoughts to consider when building your own personal PC
As always Id personally use PCPartPicker.com to configure your parts and for further thoughts on compatibility.
First off building a computer is 100% based around what you plan to use the computer for.
Here are a few uses and generic ideas of what to go for. Audio Editing: Lots of small tasks that need to be completed quickly without lag. - Fast Processor( >4GHZ) - Fast RAM (MHZ) -At least 16 gigs! - Fast Storage, SSD manditorily - M.2 or PCI for best performance. - Shitty Graphics card, graphics card there only to keep the cpu from doing other tasks when working. - Can be a few generations or years old. - Many screens for lots of plug in windows to be open Video Editing: Lots of large to render and files to read. - Multi core processor the more the merrier - SSD for fast read/write of large video files. - Insane graphics card, AMD graphics cards are debatibly better but the nvidia Quadro series are specific for video rendering. Gaming: No more than 4 cores intense graphics card - 92% of games are not coded for more than 4 cores so why spend the extra money for it. - SSD for quick load screens - Nvidia cards, 10 series, the higher the number the better. Titan cards for MAXIMUM OVERDRIVE! Coding: quick processor for lots of small tasks. Ergonomic peripherials? - Dear god please dont use a mechanical keyboard so that your coworkers dont kill you. Home office: Everything can be a few gens behind so you can get the best power per dollar spent. - Sorry that Gateway doesnt exist anymore. I guess try Dell... 
Parts (Expensive Legos)
CPU (tells things to go places and outputs data) Basically three main routes to go for: Intel, AMD, or ASIC. Intel - Gaming, Data center, Hackintosh Pros: Cooler, Faster speed (GHZ), short small tasks faster Cons: $$$$, less cores AMD - Gaming, Personal Computing, Large task processing Pros: Lots of cores, better price per performance, faster processing of large tasks Cons: Hot chips, large chips?, compatibility issues with MacOS. ASIC - "Application-specific integrated circuit" Pros: Does the task that they are made to do insanely efficently, great for mining. Cons: Literally does nothing else. Holy hell these are expensive, very hot (fans will get loud) CPU Cooler (Im a big fan) Most come with an in box cooler that are ok but please buy aftermarket. In Box - the free shitty cooler that comes with the processor. Pros: Free. Cons: Ugly, makes chip run hot, hard to clean Air cooler - oldest type of cooler but new designs are highly efficent. Pros: Only cooler that has the possibility of being 100% quiet, most likely cheaper Cons: large, if cooler isnt large enough for the chips thermal output the fans will be loud. Liquid - Custom pipes are beautiful, AIO is easy to install and offers similare performance. Pros: Looks cool, great temperatures, "quiet" Cons: Water pump has possibility of being loud, possible spills Phase Change - uses the technology of refridgerators to cool the chip Pros: Can overclock until the chip breaks. (whats colder than cold? ICE COLD!) Cons: Loud (compressor noise), Large pipes, just why.... Motherboard (the convienacnce store of computer parts) Really just about what type of I/O you want. - MAKE SURE FORM FACTOR FITS YOUR CASE! (or vice versa) - Look for PCI lanes for expansion. - How many graphic cards do you have? - PCI based interfaces? - PCI SSD? - PCI DAC? - PCI WIFI? - USbs? Network? Audio? - How many lanes of RAM? - DOES IT FIT YOUR PROCESSOR!?! (really tho) - M.2? - How many sata interaces? Good Brands: MSI, ASUS, Gigabyte Bad Brands: AS(s)Rock, Dell Memory (Dory) - The more the merrier - No less than 8gb for a functional windows machine (16 gb to never have a problem) - Use all the lanes your computer has to offer! the more lanes to access the faster the data can travel! -Imagine drinking a milkshake. If the straw is wider you can drink more of the milkshake than a skinny straw. - Faster MHZ for faster data access but give minimal performance differances - Please get ram with heat spreadders unles youre building a server with high airflow. - Make sure the type (DDR3 or DDR4) of RAM matches what your processomotherboard call for. Good Brands: Corsair, G.Skill, Ballistix Storage (Grandpa that remembers everythign about how things used to be but takes forever to learn a new tasK) Speed or massive storage? slower is cheaper. Golden ratio of speed/storage/price is 250-500 gb SSD and a 1+ tb disk drive. *Max speeds listed are for a single drive not RAID* Hard Disk Drives (HDD) - Cheapest and slowest - read/write speeds of < 0.5gb/s - 7200+ RPM or GTFO - Higher Speed drives can access data faster. - Do not move while powered up. physical parts will break. - Larger Cahche = faster Read/Write Speeds Pros: Cheap, Holds massive amounts of data Cons: Slower than molasses in a frezer Reputible Brands: Seagate, WD Solid State Drives (SSD) - necessity for quick boots and fast load screens (can only be re-written to so many times) - SATA based (2.5 inch)- Read/Write speeds capped @ 6 gb/s Pros: Most economical, form factor fits with old computers, Cons: "Slow" compared to other ssd's (but stil 12 times faster than a HDD) - M.2 based - Read/Write speeds capped @ 10 gb/s Pros: Size of a sick of gum! High End but not too expensive to be out of reach. Cons: Expensive for any size over 500 gb - PCI based - Read/Write speeds capped @ 20 gb/s for PCI3, x4 Pros: HOLY BANDWIDTH BATMAN! Faster than that little creepy ghost thats always in the corner of you eye Cons: You might have to take out a loan to buy one. *takes up a x4 PCI Lane* Reputible Brands: Samsung! Corsair, Plextor, Intel, Kingston, Crucial Video Card (that one kid that has thick glasses and is really good at math) - A regular old PCI card that handles all of the video rendering and output for your computer. - ASIC PCI cards. - The PCBs and chips are patented by two main companies but the differances come from line up and varying manufacturer cooling devices. - The more memory the better -NVIDIA (Team Green) Great for gaming, has specific card series for intensive rendering. Lazy driver updates. - Gaming - 900 series - Cheap - Low performance - Can play any video game made befrore 2010 on max settings - 1000 (ten) series - Expensive (thanks bitcoin miners...) - Great for VR! - Video Rendering -Quadro Series - Gaming and Rendering - Titan X - Maxwell based chip same as 900 series cards - Titan XP - Pascal based chip same as 10 series cards -AMD (Team Red) Underdog does the same thing but slighly worse and cheaper. (except video rendering) - Gaming - RX 400 series - Cheap - Hot - RX 500 series - Cheap - Ok at VR and deacent gaming frame rates. - Not bad but not particularly great either. - Video Rendering - Fire Pro series - Gaming and Rendering - Vega series -Good luck finding one to buy lmao Case (Fancy clothing for your parts!) - Similar to human clothing you want it to do a few main things really well with compromises for each extreme. - Durability - Steel - Incredibly durable - Creates Farady cage for components - Heavy af - Magnets, just magnets.... - Rust over time - Aluminium - Light - East to bend for modding or "physical maintenance" - Less likely to rust - Huzzah for Farady cages! - Plastic - Just dont - no electrical Ground - no faraday cage - Light AF! - Breath (Airflow) - positive internal airflow! - larger fans push the same amount of air with less speed/noise - Looks - Window? - RGB - Cool Paint? - Fit all your parts - graphics card length/ clearacne - support for liquid cooling raiators? - How many spots for HDD/SSDs - Motherboard format - Cable management! Power Supply (FIGHT MILK) - Rule of thumb: BUy Powersupply that outputs 1.5 times the wattage that you need. - You can walk further than you can you can run. - The PSU can casually output 50-75% power for much longer than at 90-100% (without failure) - If you never demand enough wattage for it to get hot the fan doesnt have to turn on therefore making it quieter. - Modular means you can remove/replace the cables from the PSU. Reputible Brands: Corsair, EVGA Optical Drive (motorized cup holder) - You can download most things today so I'd suggest against it unless you really NEED to watch/write DVD's/CD's Operating System (software that makes everything work) Windows (Always Updates) - Compatible with just about everything - Easy to learn to code on! - POS inital browser - Likely to get virus's Linux (Penguins are cute) - Unique - takes less resources to run - Barebones - Incredibly personalizable! - Compatibility issues with just about everything MacOS (Linux but more annoying) - It is legal! - Great for art and your grandma that doenst know how to use computers! - User friendly - Compatibility issues with various hardware - Confusing/Limiting coding structure Peripherials (cables everywhere!) - Keyboard (higer Polling rate is better) - Mechanical (key is pressed at an exact stroke length every time - Mouse (Higher Polling rate is better) - more buttons = better? - DPI (Dots Per Inch) - In theory, if a mouse has 1600 DPI, then, if you move your mouse one inch (2.54 cm), the mouse cursor will move 1600 pixels - Higher DPI the faster your cursor is able to be moved. - Monitor - In theory the human eye cant see faster than 60 frames per second. - Keep in mind Pixel ratio! - 4k screen that is 22inches will have more pixels in a square inch than a 4k screen that is 28 inches. - Interface? - DVI (Analog) - thumbscrews..... - can do two monitors with one port! - support for 4k - VGA (Analog) - thumbscrews... - max resolution is 1440p - Display Port (digital) - nice button clip - supports 4k - HDMI (Digital) - 1.2 or higer supports 4k - DAC/Speakers/Headphones - Dont even get me started - Microphone - Dont get me started PT.2 Other (other) - UPS (uninterruptible power supply) Just a battery that allows your computer to have some time if the power ever goes out so that you have time to save your work. - Cable Organization materials! - Zipties - velcro - LED LIGHTING! - Manditory - Extra/Better fans - More pressure, less woosh - IFIXIT Pro Tech Toolkit - becasue who buys just one torx wrench. - Cute kitten mousepad - Yes, it has to be a cat. Dont argue 
This is a very general entry into building computers and what you should buy/look for. If you have any questions/comments send me an e-mail!

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

#support is not often mentioned, but it must be noted that every day on this channel people get high quality support. (@bee: To my surprise, even those poor souls running Windows 10. My greatest respect to the support team!)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

Relevant External

ASIC for Lyra2REv2 was spotted on the web. Vertcoin team is preparing a new PoW algorithm. This would be the 3rd fork after two previous forks to change the algorithm in 2014 and 2015.
A report titled The Positive Externalities of Bitcoin Mining discusses the benefits of PoW mining that are often overlooked by the critics of its energy use.
A Brief Study of Cryptonetwork Forks by Alex Evans of Placeholder studies the behavior of users, developers and miners after the fork, and makes the cases that it is hard for child chains to attract users and developers from their parent chains.
New research on private atomic swaps: the paper "Anonymous Atomic Swaps Using Homomorphic Hashing" attempts to break the public link between two transactions. (bitcointalk, decred)
On Sep 18 Poloniex announced delisting of 8 more assets. That day they took a 12-80% dive showing their dependence on this one exchange.
Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.".
Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred)
The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights.
A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

What is the amateur friendly way to get into mining?

I want to do some mining, as a hobby, with no focus on profitability, but learning about computers and crypto will be a reward in itself.
Right now, I have an old laptop I have mining at a very low rate, which is fun but I want to get a little more serious.
It seems I have a few options. I could assemble a mining rig with multiple GPUs, while keeping the budget around 1000 bucks (lil more probably). I worry about the cost of this approach, but it would also yield the most experience.
The other options seem to be buying specific mining hardware like an ASIC miner (seems very expensive) or I saw USB miners like the mooonlander2 which seemed good for a hobbyist (like myself) but they are too plug & play, so I would learn less.
Yall have any suggestions? I know this is a very pricey time for components, and I also dont wanna spend money and have my miner become obsolete too quickly. I've been lurking and reading the sidebars of various mining subreddits, but I'm still struggling to decide on an approach.
I don't much care about which coins I mine. Probably not bitcoin, since that seems too hard for the hobbyist. (though perhaps Im mistaken)

Bitcoin Mining Profits: Crypto Mining Hardware or Cloud Mining Pools?

Can Cloud Mining Be More Profitable Than Getting Mining Hardware For Bitcoin?
The process of crypto mining demands a lot of preparation, no matter which cryptocurrency you choose. Mining Bitcoin (BTC), however, requires even more.
If you are a Bitcoin miner, or you at least researched the issue, you probably quickly realized that this is quite a difficult process. There a lot of aspects of the process that need to be considered, like the Proof-of-Work’s mining algorithm, fees, and hashing power. Not to mention the extremely expensive equipment that is necessary in order to do it.
However, there is another option which may be more profitable, and that is cloud mining. But is it really the best way to go? Let us find out.
Bitcoin Miningining: Hardware & Cost
Let’s start with the necessary mining hardware. In order to mine Bitcoin, you cannot just use anything, and in order to get a quality device, you will have to prepare quite a sum in advance.
Bitcoin mining hardware can cost from a few thousand dollars to tens of thousands of dollars. The price largely depends on which crypto you wish to mine (in this case, Bitcoin), as well as how big of a mining operation you are planning.
The cost of a mining rig depends on which one you want. You might go for an ASIC mining rig, or a GPU and CPU mining rigs. ASIC mining rig is usually far more expensive, and their hash rates are a lot faster. However, they are known for facing scrutiny due to the fact that you cannot repurpose them.
Basically, if the hash algorithm of the blockchain changes, your ASIC rig will become pretty much useless, and you will have to acquire new gear. Obviously, this is the most expensive solution.
GPU and CPU gear, on the other hand, can be re-purposed. The gear is also a lot cheaper, and much more acceptable than ASIC, which often finds a lot of resistance. This is why most miners choose to go for GPU and CPU instead of ASIC.
Of course, there is always an option to have several mining rigs set up, in order to multiply your earnings. However, this means that you will have to acquire them first, which is probably the most expensive option. Even with several mining rigs working at the same time, it will probably take months before you can cover these initial costs via mining. Not to mention other factors, like the cost of an electric bill that is going to skyrocket as soon as you start your mining operation.
The electricity cost varies depending on your location, which makes it hard to precisely calculate the cost of keeping the operation up and running.
Cryptocurrency Cloud Mining Pools: Profitable or Not?
Calculating the costs of cloud mining, on the other hand, is a much easier process. A lot of companies are using monthly subscriptions, with their cost being determined by the targeted crypto that the user wants to mine. Additionally, the cost of the model is also determined by the hash rate speeds.
For example, taking a contract for 2 years of mining Ethereum with Genesis Mining can cost anywhere between $1,520 and $12,960, depending on the speed which can go from 40 MH/s to 360 MH/s.
On the other hand, there is a website called HashFlare, which can provide you with a contract that lasts only one year, and it costs $1.80 for 100 KH/s.
The fact is that cloud mining is expensive as well, and not that profitable at first. You will probably need more than a year to cover the cost of the initial investment. A lot of people don’t do their research properly, which is why they enter the process expecting to get rich in less than 6 months. This is, of course, never the case.
Generally, cloud mining is not that profitable at all. Because of that, it is also not the popular way of crypto mining. Monthly subscriptions will always be there, but it won’t always be easy to pay them off. There are always the USB mining options but they are not very powerful.
If you choose to go with the mining hardware, the costs will be upfront, and you will know what you are getting into. The cost of electricity will be a bit more difficult to predict, but if you can afford to perform your mining operation in parts of the world where the electricity is cheap, and mining is legal, you can actually make a pretty good profit much faster.

What is Bitcoin?
Bitcoin is an experimental system of transfer and verification of property based on a network of peer to peer without any central authority.
The initial application and the main innovation of the Bitcoin network is a system of digital currency decentralized unit of account is bitcoin.
Bitcoin works with software and a protocol that allows participants to issue bitcoins and manage transactions in a collective and automatic way. As a free Protocol (open source), it also allows interoperability of software and services that use it. As a currency bitcoin is both a medium of payment and a store of value.
Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed homogeneously by computing the network power, and will be limited to 21 million divisible units up to the eighth decimal place. The functioning of the Exchange is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms, programs making them operational, the data of accounts and discussions of the developers.
The possession of bitcoins is materialized by a sequence of numbers and letters that make up a virtual key allowing the expenditure of bitcoins associated with him on the registry. A person may hold several key compiled in a 'Bitcoin Wallet ', 'Keychain' web, software or hardware which allows access to the network in order to make transactions. Key to check the balance in bitcoins and public keys to receive payments. It contains also (often encrypted way) the private key associated with the public key. These private keys must remain secret, because their owner can spend bitcoins associated with them on the register. All support (keyrings) agrees to maintain the sequence of symbols constituting your keychain: paper, USB, memory stick, etc. With appropriate software, you can manage your assets on your computer or your phone.
Bitcoin on an account, to either a holder of bitcoins in has given you, for example in Exchange for property, either go through an Exchange platform that converts conventional currencies in bitcoins, is earned by participating in the operations of collective control of the currency.
The sources of Bitcoin codes have been released under an open source license MIT which allows to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to insert a copyright notice into all copies.
Bitcoin creator, Satoshi Nakamoto
What is the Mining of bitcoin?
Technical details :
During mining, your computer performs cryptographic hashes (two successive SHA256) on what is called a header block. For each new hash, mining software uses a different random number that called Nuncio. According to the content of the block and the nonce value typically used to express the current target. This number is called the difficulty of mining. The difficulty of mining is calculated by comparing how much it is difficult to generate a block compared to the first created block. This means that a difficulty of 70000 is 70000 times more effort that it took to Satoshi Nakamoto to generate the first block. Where mining was much slower and poorly optimized.
The difficulty changes each 2016 blocks. The network tries to assign the difficulty in such a way that global computing power takes exactly 14 days to generate 2016 blocks. That's why the difficulty increases along with the power of the network.
Material :
In the beginning, mining with a processor (CPU) was the only way to undermine bitcoins. (GPU) graphics cards have possibly replaced the CPU due to their nature, which allowed an increase between 50 x to 100 x in computing power by using less electricity by megahash compared to a CPU.
Although any modern GPU can be used to make the mining, the brand AMD GPU architecture has proved to be far superior to nVidia to undermine bitcoins and the ATI Radeon HD 5870 card was the most economical for a time.
For a more complete list of graphics cards and their performance, see Wiki Bitcoin: comparison of mining equipment
In the same way that transition CPU to GPU, the world of mining has evolved into the use of the Field Programmable Gate Arrays (FPGA) as a mining platform. Although FPGAs did not offer an increase of 50 x to 100 x speed of calculation as the transition from CPU to GPU, they offered a better energy efficiency.
A typical HD/s 600 graphics card consumes about 400w of power, while a typical FPGA device can offer a rate of hash of 826 MH/s to 80w of power consumption, a gain of 5 x more calculations for the same energy power. Since energy efficiency is a key factor in the profitability of mining, it was an important step for the GPU to FPGA migration for many people.
The world of the mining of bitcoin is now migrating to the Application Specific Integrated Circuit (ASIC). An ASIC is a chip designed specifically to accomplish a single task. Unlike FPGAs, an ASIC is unable to be reprogrammed for other tasks. An ASIC designed to undermine bitcoins cannot and will not do anything else than to undermine bitcoins.
The stiffness of an ASIC allows us to offer an increase of 100 x computing power while reducing power consumption compared to all other technologies. For example, a classic device to offer 60 GH/s (1 hashes equals 1000 Megahash. 1GH/s = 1000 Mh/s) while consuming 60w of electricity. Compared to the GPU, it is an increase in computing power of 100 x and a reduction of power consumption by a factor of 7.
Unlike the generations of technologies that have preceded the ASIC, ASIC is the "end of the line" when we talk about important technology change. The CPUs have been replaced by the GPUs, themselves replaced by FPGAs that were replaced by ASICs.
There is nothing that can replace the ASICs now or in the immediate future. There will be technological refinements in ASIC products, and improvements in energy efficiency, but nothing that may match increased from 50 x to 100 x the computing power or a 7 x reduction in power consumption compared with the previous technology.
Which means that the energy efficiency of an ASIC device is the only important factor of all product ASIC, since the estimated lifetime of an ASIC device is superior to the entire history of the mining of bitcoin. It is conceivable that a purchased ASIC device today is still in operation in two years if the unit still offers a profitable enough economic to keep power consumption. The profitability of mining is also determined by the value of bitcoin but in all cases, more a device has a good energy efficiency, it is profitable.
Software :
There are two ways to make mining: by yourself or as part of a team (a pool). If you are mining for yourself, you must install the Bitcoin software and configure it to JSON-RPC (see: run Bitcoin). The other option is to join a pool. There are multiple available pools. With a pool, the profit generated by any block generated by a member of the team is split between all members of the team. The advantage of joining a team is to increase the frequency and stability of earnings (this is called reduce the variance) but gains will be lower. In the end, you will earn the same amount with the two approaches. Undermine solo allows you to receive earnings huge but very infrequent, while miner with a pool can offer you small stable and steady gains.
Once you have your software configured or that you have joined a pool, the next step is to configure the mining software. The software the most populare for ASIC/FPGA/GPU currently is CGminer or a derivative designed specifically for FPGAS and ASICs, BFGMiner.
If you want a quick overview of mining without install any software, try Bitcoin Plus, a Bitcoin minor running in your browser with your CPU. It is not profitable to make serious mining, but it is a good demonstration of the principle of the mining team.

My first 30 days running a Bitcoin only E-commerce business.

The MineNinja store, www.mineninja.com, has been up for a month now, so I figure its a good time to reflect on the whole experience of running a business that accepts Bitcoin exclusively. I’ve run other E-commerce websites, mainly selling digital products for PayPal. In my previous experiment I tried adding Bitcoin payment to one of my best performing products and honestly got less than stellar results even offering a huge discount.
After studying the market I determined that a better path was to offer a product that would appeal to one of the core segments of the Bitcoin participant population: Bitcoin miners. The MineNinja is a Bitcoin mining controller for managing USB connected ASIC devices.
I underestimated how difficult the whole process would be from manufacturing to shipping. The first few orders were very painful to fulfill. There were many late nights spent trying to dial in the packaging and shipping. 3d took some time to get dialed in correctly, and we threw away a ton of failed prints. It was a great learning experience.
I also learned that keeping everything denominated in Bitcoin is risky. When the price of Bitcoin fell, and I didn’t update my pricing quick enough, we had sales that resulted in a net loss. I could eliminate this risk by pricing in USD, but it’s a matter of principle to keep it all Bitcoin.
I didn’t do any sort of advertising, no Adwords or anything like that. All I have done is just a few posts on bitcoin and Bitcoin related forums. I did a total of 28BTC worth of sales for the first month.
Expenses:
Startup Investment - 3D printer: $2195
Cost of Goods Sold:
The USD denominated supplies were personally funded. I am trying to keep all the BTC earnings in BTC. I am moving my supply chain to Bitcoin as practical. I found a cool 3d Printer company www.makergeeks.com that accepts Bitcoin payments so next month’s personal finances will be a little better. I’m still having to pay USD to buy the boards as I have not yet found a supplier that accepts Bitcoin payment.
I don’t think my decision to go with a completely open source solution hurt sales too badly. Most customers chose the more expensive ready-to-mine options over the build-your-own. I got hit hard for BeagleBones when the BTC price dropped, and I didn’t adjust prices, but thankfully my low inventories and a recent rebound in price insulated me from disaster.
Now that I have shut down my GPUs, I can move the business from the dining room table to the room we now refer to as the "crap room." The big weekend project is to clean it out and convert it into the CoinNinja headquarters.
I’ve got quite a few cool things planned for the MineNinja project and other CoinNinja Open Source projects. Stay tuned.

Updated FAQs for newcomers

TL:DR: Don't bother mining if you want to get rich yo. You're way too late to the party.
Welcome to the exciting and often stressful world of bitcoin! You are wondering what looks like a once in a lifetime opportunity to get rich quick. Of course you guys probably heard about this "mining" process but what is this?
Simply put, a bitcoin mining machine that performs complicated calculations and when deemed correct by the network, receives a block which contains 25 bitcoins (XBT). This is how bitcoins are generated. So your brain instantly thinks, "Holy shit, how can I get on this gold rush?"
Before you proceed further, I would like to explain the concept of mining further. Bitcoin is limited 21m in circulation. It is coded to release a certain number of blocks at a certain time frame, ie: this year the network will release close to 500,000 bitcoins. What this means is that the more people (or specifically the amount of mining power) mine, the less each person gets. The network tries to keep to this time frame through the process of difficulty adjustments which makes the calculations harder and this happens every 2 weeks. So every 2 weeks, you get less bitcoins with the same hash rate (mining power) based on what the difficulty changes are. Recently, the changes have been pretty staggering, jumping 226% in 2 months. You can see the difficulty changes here.
Now, why are these changes so large?
A bit of a simple history. Bitcoin's algorithm runs on SHA-256. This algorithm can be solved using many hardware, from CPU to GPU and dedicated hardware (Application Specific Integrated Circuits). When bitcoin first started, mining on CPU was a trivial process, you can pretty much earn 50 XBT (the block size then) every few hours between Q1 and Q2 of 2010.
In late 2010, due to the difficulty increase that is reducing the effectiveness of CPU mining, people started to harness GPU mining. Only AMD GPU's architecture design are better optimized for bitcoin mining so this is what the community used. Immediate improvements of more than 10x was not uncommon.
In time of course, GPUs reached their limit and people started to build dedicated. In the same vein as the CPU to GPU transition, similar performance increase was common. These ASICs can only perform SHA-256 calculation so they can be highly optimized. Their performance mainly depends on the die size of the chips exactly like CPU chips.
In general, think of bitcoin mining's technological advancement no different to mining gold. Gold panning (CPUs) vs pickaxes (GPUs) vs machinery (ASICs) and we are still in the ASIC mining race.
ASIC mining started with ASICMiner and Avalon being first to the market, both producing 130nm and 110nm chips. The technology are antiquated in comparison to CPUs and GPUs which are now 22nm with 14nm slated for Q1 next year by Intel but they are cheap to manufacture and with performance gains similar to the CPU to GPU transition, they were highly successful and popular for early adopters. At that point in time since there were less competing manufacturers and the low batch runs of their products, miners became really rich due to the slow increase in difficulty.
The good days came to an end mid August with an unprecedented 35% increase in difficulty. This is due to existing manufacturers selling more hardware and many other players coming onto the market with better hardware (smaller die). Since die shrinking knowledge and manufacturing process are well known along with a large technological gap (110nm vs 22nm), you get an arms race. Current ASIC makers are closing in on our technological limit and until everyone catches up, the difficulty jumps will be high because it is just too easy to get a performance increase. Most newer products run at 28nm and most chips are not well optimized, so it will be around another 6 to 9 months before we see hit a hard plateau with 22nm or 14nm chips. The estimated time frame is because manufacturing chips at 22nm or 14nm is a more difficult and expensive task. In the meantime most manufacturers will probably settle at 28nm and we will reach a soft plateau in about 3 months.
Now, you might ask these questions and should have them answered and if you have not thought about them at all, then you probably should not touch bitcoin until you understand cause you are highly unprepared and probably lose lots of money.
No. If you have to ask, please do not touch bitcoin yet. You will spend more on electricity cost than mining any substantial bitcoin. Seriously. At all. A 7990 would produce a pitiful 0.02879 XBT (USD $14 @ $500/XBT exchange rate) for the next 30 days starting 23 Nov 2013 at 35% difficulty increase.
And if you think you can mine on your laptop either on a CPU or GPU, you are probably going to melt it before you even get 0.01 XBT.
Probably not because you probably forgot that GPUs and CPUs produce a ton of heat and noise. You can try but I see no point earning < $20 bucks per month.
No, because your machine will probably not mine as much as buying bitcoins. This situation is called the opportunity cost. While you can still make money if XBT rise in value, it is a fallacy.
IE: if you start mining on 1 Dec 2013, a KnC Jupiter running at 450Gh/sec (KnC lies as not all chips run at 550Gh/sec) will yield you a total revenue of 9.5189 XBT with a profit of 0.7859 XBT in profit by 30th Jan 2014 at a constant difficulty increase of 35%. The opportunity cost is: 8.5910 XBT @ USD $580/XBT with USD $5,000 which is the cost of a KnC Jupiter. This is the best you can earn and it's a bloody optimistic assumption because:
The only circumstances where you will earn money is when XBT exchange rates is so high that it makes the opportunity cost pales in comparison. Unfortunately this is not the case. If XBT stabilized at 900/XBT today (20 Nov 2013) then we might have a good case.
The risk is just generally not worth it. Unless you have at least a hundred thousand and can make a contract with a manufacturer for a lower cost, do not bother. Just wait until the arms race is over then you can start mining.
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
Sure, just read the answer below on who NOT to go for. You are doing bitcoin a service by securing the network and you have our (the users') gratitude.
You can check out the manufacturers and their products below along with a calculator here.
If you still insist on buying, do not to go for BFL. Their track record is horrid and borderline scammish. KnC fucked up a lot with defective boards and chips. Personally, I think CoinTerra is the best choice.
Alternatively, you can go on the secondary market to buy a delivered product. You can get a better deal there if you know how to do your "return on investment (ROI)" calculation. Personally, I will go for a 45%-50% difficulty increase for the next 3 months for my calculations and a 2% pool fee.
However, most products on ebay are sold at a cost much higher than it should. bitcointalk.org is a cheaper place because everyone knows what are the true value is so you will find less options. If you are unclear or need assistance, please post a question.
I actually do not use any of the pools recommended to the left because I think they lack features.
My favourite is Bitminter (Variable fees based on features used; max 2%). It has all advanced features for a pool, very responsive and helpful owner on IRC. Variable fees is good for those who do not need a large feature set, even with all features turned on, it is still cheap.
Eligius (0% fees) has high value for money but lacks features. It has anonymous mining which might be attractive to certain subset of people but not for others. Many other community member and I disagree highly with the opinions of the owner on the direction of bitcoin. I do use his pool for now but I do so only because I share my miners with a few partners and anonymous mining allows us to monitor the machines without using an account. Bitminter uses only OpenID which is problematic for me.
BTC Guild (3% fees) is another big pool and is fully featured and does charge a premium for their fees. That said, they are the most stable of the lot. I do use them but do so only because my hoster uses them for monitoring. I try not to use them because a pool with a very large hash rate (they are the largest) presents a large vulnerability to bitcoin's network if compromised.
All of them pay out transaction fees.

Frequently Asked Question: What's an ASIC, FPGA?

So you're sick of just mining on your GPU, and not a fan of the electric bill after a month of mining? There has to be a better option out there than your loud GPU in your gaming computer. There is!
Shortly after GPUs became popular for bitcoin mining, enterprising folks started looking at other things they can re-purpose to mine bitcoins more efficiently. Around mid-year 2011, the first devices sprang up that are called FPGAs or Field Programmable Gate Arrays. These are nothing new to the hobbyist community, they've been around for a while for crackers and other security-conscious folks looking at ways to defeat cryptographic locks. Hey! I know something that uses cryptographic calculations to secure its network! BITCOINS! Yep, so some miners developed their own boards and slapped some FPGA chips on them (most commonly the Spartan-6), and wrote specific firmware and "bitstreams" to more efficiently calculate bitcoin hashes. The first generations were sort of slow, but still they had better efficiency than a GPU. Some of the latest generation included the Icarus boards, Cairnsmore, x6500, and ModMiner Quad.
In early 2012(i think my timeline is right), Butterfly Labs(BFL) was selling their own FPGA miner that hashed at 800 Mhash/s using 80 watts and only cost US$600 amazing! These grew very popular, but people could see that FPGAs still weren't the most efficient way to hash their shares. BFL then announced that they would be designing their own chips that would be orders of magnitude faster than anything ever seen. These would be the ASICs (or Application Specific Integrated Circuit)everyone is raving about. ASICs are--as the name implies--specifically designed for one thing, and one thing only. Bitcoins. This is all it can do, and can't really be repurposed like an FPGA to other applications. Who wouldn't want a US$150 "Jalapeno" that hashes at 3.5 GIGAhashes/s using only power from a USB port?? Crazy! So summer 2012, BFL says they will ship before Christmas. Various things happen and we now still don't have any confirmed ship dates from BFL.
A few other companies have sprouted up, ASICminer which I believe is developing their own chips to mine themselves, but in a responsible way as to not threaten the network with a sudden influx of hashing. bASIC was a fiasco that was developed by the creator of the ModMiner Quad(which is actually a fantastic miner, I own one, and love it.) where he took many preorders, promised lots of people amazing ASIC performance, but in early 2013 the stress of the whole endeavour got to him and he gave up, refunded money(I think it's still being refunded now, or maybe it's been cleared up already.)
Avalon is the only company we know has ASIC mining hardware in the wild. It is not certain exactly how many are out there, but they have been confirmed by independent sources. The Avalon units are expensive(75 BTC) and have been in limited production runs (or batches) of a few hundred units that were pre-sold out very quickly.
All of this info is gleaned from the Custom Hardware forum over at bitcointalk.org over the past year or so I've been involved in bitcoin. I may have some facts wrong, but this is the gist of the situation and hopefully gives you an insight on the state of the hardware war against bitcoin
Thanks for reading!

The Anatomy of Genesis Mining Rig

Crypto mania is taking the world by storm! From reaching a combined $600 billion market cap, to Bitcoin trading at $20k on some exchanges, there seems to be no stopping the rise of digital currencies.
There are many ways to cash in on the potential that crypto has to offer, one of them being mining. This is the process where each transaction or record on the blockchain network is verified. As a reward for their contribution to the network, the miners receive freshly generated cryptocoins.
The cryptocurrency mining process is extremely processor as well as power intensive, and can get expensive if tried individually at home. Not to mention, the mining process requires specialized hardware, which has to be set up by oneself along with the power supply to feed the hardware. Genesis Mining steps in here to make the whole process easier, allowing interested cryptocurrency community members to be part of the mining community without going through any of these hassles. On a mission to “democratize mining”, the company is providing accessible and affordable cryptocurrency mining solution to the masses.
Genesis Mining provides cloud-based mining services to small- and large-scale investors. Their mining farms already have all of the equipment set up. In fact, the platform has the best Bitcoin and Altcoin-mining hardware and software available and running already.
The representatives of Genesis Mining have recently taken an initiative through their “EvolveWithUs” campaign to explain cryptocurrency mining and their services in the sector to the general public to increase awareness about the process and the company’s offering.
What is a Mining Rig?
Stefan Schindler, CTO representing Genesis Mining offers a simple definition for the most crucial hardware in the mining operation by saying,
“A mining rig is basically a computer, but is stripped down to the minimum in terms of computing, and up to the maximum in terms of mining.”
The Evolution of Mining
Mining had previously been done on a computer’s processor. However, as the industry grew, so did its mining requirements. Processor mining took an enormous amount of power, and an alternative was eventually adopted — Graphic cards. Graphics Cards or GPUs, proved to be more efficient at processing transactions, and didn’t use nearly as much power, resulting in a classic ‘work smarter, not harder’ approach. Since then the industry has advanced, creating specialized hardware called ASIC miners. However, GPUs still play a vital role in mining some of the popular alternative cryptocurrencies (Altcoins) in the market.
The Structure of a Mining Rig
In appearance, it looks like your average computer mainboard. The key difference is that is filled with lots of GPUs. The USB port contains USBs holding the actual mining software, which is not stored on the processor. It also has plenty of connecting cables to make everything run.
GPU processing
In the case of Genesis Mining, their specialized mining rigs can hold about six GPUs each. The mainboards available on the market do not have the internal space or slots for all of these GPUs that goes into Genesis Mining’s version of mining hardware. This is where PCI risers come in, which are extension cables that allow the mainboard to be fitted with many GPUs. These risers also help with even heat distribution so that the rig doesn’t overheat.
The power supply unit is also fitted with a strong cable, and powers all of the GPUs and the mainboard.
The company manufactures, stores and operates the mining rings at their mining farms in Iceland and other locations. These equipment can be quickly and efficiently assembled and are completely mobile for added convenience.

Zeus/Gaw ASIC Setup Guide for Linux/Raspberry Pi

So I recently I became quite interested in mining and cyptocurrencies in general. So interested in fact that I bit the bullet and decided to buy myself a GAW Fury.
I then spent some time doing research on how to set up a GAW or Zeus ASIC on Linux, in particular on a Raspberry Pi, and have found most guides to be awful. The reason they are so bad IMHO is that they assume quite a bit of prior knowledge, either with Linux or mining, and give very little instructions. So I have tried to put together a guide that requires very little prior knowledge.
It is my aim that anyone could get their shiny new asic up and mining in no time using this guide. Anyway, I present...

The Complete Noobs Guide to Setting Up a Zeus or Gaw ASIC on Debian/Ubuntu/Raspberry Pi

Resources

About Cyrptocurrencies and Their Jargon

If you are new to cryptocurrencies and how they work I suggest taking a look at this series of KhanAcademy videos. They are for Bitcoin but the theory is the same. I found them very helpful when it came to understanding what mining actually does and the mechanics of cyrptocurrencies.
Also take a look at sircamm22 his info found here, is great and breaks down a large number of concepts. I slightly disagree with no. 21 regarding preordering. Just exercise common sense.

Linux

If you are new to Linux you could follow along by simply typing in the commands. However I highly recommend taking the time to learn what you are doing. This course is a great place to start.

Computer Setup

By the end of this section you will have your device turned on, fully setup and connected to the internet with.
Note: Commands to be typed into the command line will be displayed like this:
echo Hello World

Desktop/Laptop

For laptops and desktops already running Ubuntu or Debian I will assume you have setup your internet setup as part of the installation.
If not: There are plenty of guides out there and the installation/setup process is very easy. A good place to start for Ubuntu is here.
Now open up a terminal window. Ctrl + alt + t on a standard Ubuntu installation.
If you plan on using this PC without a monitor I would suggest installing an SSH Server.
These commands will be discussed later on in the guide.
sudo apt-get -y install openssh-server
sudo service openssh-server start

Raspberry Pi

The Raspberry Pi Foundation has put together a great guide in PDF format.
Use NOOBS it will save you a lot of trouble. NB: Some SD cards don't support NOOBs but will work fine if the image is put on using a different method.
Here is a great guide for setting up the Raspberry Pi SD card from Elinux.org. In fact it's a great place to start for anything RPi related. Raspberry Pi hub at Elinux.
Once the SD card is setup you will need to insert it into the Raspberry Pi and boot. Install Raspbian from the NOOBs menu and wait.
Follow this guide by Adafruit for first time setup. You will need to enable SSH Server.
I suggest not starting the desktop on boot. It can be easily run from the command line by typing startx.
Follow this guide by Adafruit to setup your network. Found here. No need to do this if you set up previously in the first time config.
We will also at this point want to setup ssh. Again I will point you to an Adafruit guide.
Once done exit back to a standard command line interface. This can be done in LXDE by using the power off menu located in the bottom right corner.

Miner Setup

Installing BFGMiner

If you want to the Raspberry Pi or PC without a monitor go ahead and SSH into your device.
So now you should be staring at a command line interface whether on the device with a monitor or via SSH.
First things first lets make sure we are all up to date. This will update our package list from the repositories and upgrade them to the newest version. "-y" Will simply say yes to any prompts.
sudo apt-get update && sudo apt-get -y upgrade
We are going to need to install some useful tools. Git-core is how we will clone and download BFGMiner from GitHub and Screen allows multiple command line instances and means if we exit out of ssh session or quit Terminal on Ubuntu, BFGMiner will continue to run.
sudo apt-get install git-core screen
We also need to download some other tools/dependencies to ensure that BFGMiner will compile successfully.
sudo apt-get -y install build-essential autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libncursesw5-dev libudev-dev libusb-1.0-0-dev libevent-dev libmicrohttpd-dev libc-bin
Ok now change into your home directory.
cd ~
And clone BFGMiner by Darkwinde.
git clone https://github.com/Darkwinde/bfgminer.git
Once the download has completed move into the bfgminer directory.
cd bfgminer
The following steps may take a while.
Now run autogen.sh
sudo ./autogen.sh
You will need to make the configure script execuitable.
sudo chmod +x ./configure
Now configure bfgminer
sudo ./configure CFLAGS="-O3" --enable-scrypt
Now lets make!
sudo make
Install BFGMiner
sudo make install
One more thing...
sudo ldconfig

Running BFGMiner

If you haven't already plug in your ASIC.
Just confirm your system is recognising the ASIC.
lsusb
Its output should look similar to this (no need to type this in):
Bus 001 Device 005: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Yep there it is our ASIC listed as device 005. There is no need to install any drivers, unlike in windows, as they come in the kernel.
Now lets actually start BFGMiner.
You will want to start a screen session to ensure BFGMiner doesn't quite when you exit.
"-S" is the option for starting a new screen session. You can replace "miner" with anything you like.
screen -S miner
Now you can run the commands below.
Here is a sample of what you should type. You will need to replace somethings with your own values.
sudo bfgminer --scrypt -o stratum+tcp://URL:PORT -u USERNAME -p PASSWORD --zeus-cc CHIPCOUNT --zeus-clk 328 -S zeus:/dev/ttyUSB0
Where:
URL:PORT is the address and port of the pool you wih to use. Now I won't suggest a pool. I will leave that decision up to you. If you do wish to mine DOGE take a look at this site for a list of pools and comparisons.
USERNAME this is the username you use on the pool. Every pool is different. Check your pool's website for details. PASSWORD same as above. Specific to your pool, not every pool requires one.
CHIPCOUNT this is specific to which ASIC you are using.
For GAWMiner ASIC's:
  • War Machine: 256
  • Falcon: 128
  • Black Widow: 64
  • Fury: 6
For ZeusMiner ASIC's:
  • Blizzard: 6
  • Cyclone: 96
  • Hurricane X2: 48
  • Hurricane X3: 64
  • Thunder X2: 96
  • Thunder X3: 128
Now to make sure you don't stop mining when you exit ssh or terminal. Press:
ctrl + a + d
To come back to the BFGMiner screen simply run:
screen -r miner
You're done!!

Start on Boot

First off you will want to make sure you have BFGMiner running correctly. Ensure you have the miners set up properly and your pool correctly configured.
Start a BFGMiner instance, detailed above.
Once the instance has started and you are happy with how everything is working press "s" on your keyboard to enter the settings menu.
Now press the "w" key. Don't press enter. We want to specify where our config will go. Type:
/home/USERNAME/bfgminer.conf
Substitute USERNAME for your user. On a standard RPI install its pi. On ubuntu it's what you set during the instillation.
Now press the enter key to return back to the main BFGMiner screen. Press "q" on your keyboard to exit BFGMiner. You should now be back in the command line.
Now we want to edit a file called rc.local. Any commands in this file will be executed on boot.
sudo nano /etc/rc.local
Depending on your system this file may already contain some commands. Be careful not to delete them.
After the last command and before "exit 0" type the following on one line:
sudo -u USERNAME screen -d -m sudo bfgminer --config /home/USERNAME/bfgminer.conf
Where USERNAME = your username
Hit ctrl + x then y to save and exit nano.
The above command will create a new screen session and run bfgminer using the config we created earlier. All while as our username so that we can easily reattach.
Lets reboot to ensure it is working correctly:
sudo reboot
Once rebooted and logged in, show all running screen sessions:
screen -ls
Reattach to the session. You only need to use the numbers before the first dot.
e.g Mine looks like: 2480..hostname (13/07/14 12:02:09) (Detached). So I type:
screen -r 2480
Verify everything worked as expected. Then ctrl + a + d to exit.
You have now setup BFGMiner to restart on reboot.

Power Failure

If you are using a Raspberry Pi and it loses power it will automatically reboot on receiving power again.
For standard desktop PCs there is an option in some BIOS/UEFI to turn the computer on when it receives power. Consult your motherboard's manual and manufacturer's website.

Sources

Here is where I got my info from.
And of course /dogemining

Wrap Up

Congrats you've done it. You have managed to successfully get your shiny new asic mining away.
I do plan to make another guide detailing how to setup and use StarMiner a ready to go RPi mining distro.
So I hope this is helpful for you guys. I have seen lots of posts asking the exact same questions again and again and I have tried to answer these as best I can. I am still learning about this stuff so if there is something I have missed or a mistake I have made please tell me.
Anyway good luck. And I'll see you at the moon.
Cheers Frogsiedoodle
Edit 1: Layout and formatting.
Edit 2: Added instructions for screen which I initially forgot.
Edit 3: Removed 1 unneeded dependency
Edit 4: Added section on start on reboot and power failure.

Some pieces I cannot put together

I've been reading extensively on bitcoin for the past few days and there are a few holes here and there that I'm trying to understand. So far it makes me believe that this whole mining thing is some sort of elaborated scam. Here is a few unorganized points that are confusing to me.
Why are other currencies like litecoin slowly becoming popular and why people want them to become popular? What purpose do litecoin serves that bitcoin doesn't? If the second to bitcoin, a redundant currency like litecoin becomes popular and that people want it to become popular, then what's stop more of those currencies to all becoming popular making each of them just spammy/redundant at the end, don't we only need one of those currencies to serve the purpose of worldwide decentered transactions?
The so popular and referred mining hardware comparison sheet gives a list of videocard that are recommended to use. Combined with this calculator people can make some calculations to see if they should invest electricity cost into mining.
Now it seems to yield a little free income at the end of the month, all seems well until you investigate further. The power consumption of your videocard shown there is, in the radeon 6850 case, only half of what it truly use at full usage.
Now to add to this, I've been mining for more than a day at full power without stopping nor interfering in the process. It tells me I should be making 0.0125 bitcoin a day but I barely made half of that in a bit more than a day, yet I am positive the videocard ran at full strength for the whole process.
Now, double electricity cost vs half production, it becomes almost a profitless operation. To this, combined that the current bitcoin value is tenfold what it was 3 months ago, how could it have been profitable back then if it is not right now?
Now another suspicious part to me is those 2 websites 1 2. They offer what every person would ever want, a way to make a lot of money easily.
Both of them deliver their products months after purchase and, the 2nd website especially, is selling something that would potentially pays for itself back in less than a month, after which huge profit would come in. How convenient, to sell something that yields huge profit and pays itself back so quickly, better sell than use ourselves right?
The first site has sold out, and funnily enough are selling the next batch for 75 bitcoin per... which they could just mine themselves faster than their delivery time, so what's their gain really? Conveniently we have the 2nd website, not sold out, selling something similar to the 1st website, without any pictures of what the behind of their miner looks like, who won't mention anywhere the power consumption of their product but say that it comes with a usb cord, plug and play!
That sure not sound fishy at all since the asic counterpart is shown on the comparison sheet as using 600 W, for sure the usb connector hole can output that kind of power right?
Hopefully someone can shed some light on all this to the better understanding of least common asked matters, yet quite important for anyone who wants to jump in this... bandwagon...
I'm legitimately trying to see things optimistically but so far I only see a few root members trying to scam the entire world by projecting this half legit currency world unto us.
Note: sorry for my relatively poor english, I tried putting my thoughts into word as precisely as I could, but I couldn't do it as well as I wish I could.

Experiments in overclocking an Antminer U1 Part 2

Link to Part 1
Continuing in my attempt to overclock an Antminer U1 to 2.8Gh/s I acquired the replacement resistors, new heatsink, thermal compound, and some Chip Quik to make removing the old SMD resistors a simple task.
Heatsink: Enzotech CNB-S1
Thermal Compound: Tuniq TX2
3.74Kohm Resistor: Panasonic SMD 0603 resistor
10Kohm Resistor: Panasonic SMD 0603 resistor
The first step was to remove the 1Kohm resistor in the R1 location. After wiping the board down with an alcohol pad, adding flux, and a little dab of Chip Quik on one side of the resistor kept the solder molten long enough to heat up the other side and slide it off the board.
Antminer U1 with R1 removed
Next step was to clean off the old flux with another alcohol wipe, inspect the board to make sure I hadn't lifted the solder pad, apply more flux and solder in the 10Kohm resistor, followed by the 3.74Kohm resistor. I ordered a bunch of the 10Kohm resistor as they were really cheap, but the tolerance is 1%, so I went through a few resistors on the multimeter before finding a 10.01Kohm resistor. As there was already solder on the pads for R2 it was just a matter of using tweezers to hold the resistor in place while applying heat to one pad. After that it was trivial to just apply heat to the other end and get a good connection. The 3.74Kohm resistor is 0.1%, so I ended up settling on a 3.72Kohm out of the few I ordered. Adding the R1 resistor was as simple as the R2, though I had to add a bit more solder on the side that had been Chip Quik'd. Another clean and inspection resulted in the following.
Antminer U1 with replaced R1 and R2
The final step was to chop off the side mounts on the heatsink and drill two holes to mount the Antminer to it. A quick bit of metal cutting with a Dremel got rid of those, and also smoothed off the rough edges. I ended up having to position the Antminer at an angle on the heatsink to get it to fit nicely. A 2mm bit drilled the correct size holes to accommodate the two screws that held the old Antminer heatsink in place. I didn't have to tap threads into the drilled holes as the screws were strong enough to cut into the copper on their own. A small application of the thermal compound to the gold plated area on the back of the Antminer (refer to Part 1 images) and I attached the Antminer securely to the heatsink.
Top view of Antminer U1 attached to heatsink
Bottom view of Antminer U1 attached to heatsink
Bottom view of other side
I apologize for the awful camera potato pictures, I'll attempt to get a proper camera and take nicer ones at some point in the near future.
Now for the moment of truth, after unplugging all the other USB miners I slotted the modified Antminer and started up bfgminer running the ASIC at stock frequency. After letting it run for about an hour without anything catching on fire or exploding it was time to up the frequency. I slowly upped the frequency to 350MHz to try reach 2.8Gh/s, though at 350MHz I ran into what I'm assuming are power supply issues and the hash rate dropped to 0.8Gh/s, but didn't throw any HW errors. At 300MHz it hashes away happily at 2.58Gh/s with no HW errors, so I'll leave it at that speed for 24 hours and see what happens. Thanks for reading, hope this helps other people overclock their Antminers.

Eobot.com FAQ

FAQ https://www.eobot.com/new.aspx?referid=94984
General Questions What is a Bitcoin? Good question; see www.bitcoin.org for more information.
What are your options to withdraw? We currently only allow withdrawals in BTC/LTC/BC/NMC/DOGE/XRP/DRK/RDD/BTS/CURE/PPC/NXT/SYS.
Why can't I deposit or withdraw "real currency", aka fiat (USD/EUJPY/GBP/CNY/RUB/etc.)? Due to international law, we do not allow you to deposit or withdraw fiat currencies. In the USA, there are MSB and FinCen regulations; in Europe, certain countries have banned cryptocurrencies, and in China, the banks aren't allowed to transfer cryptocurrencies. The laws may change in the future.
Why does my "Total Cryptocurrency Value" go down? This is because that display is tied to the exchange rates on other websites. Also see this user generated YouTube video for more information: https://www.youtube.com/watch?v=GucqlMuIXMg
Are their any fees to join or monthly fees? No fees.
Do you speak Spanish/Russian/Chinese? No, only English, but Google Translator works well.
What are the maximums/minimums for withdrawing? There are no maximums. The minimums are small, see the withdraw page for details.
Where can I see the terms and conditions? Please click here for terms and conditions.
Where can I see the privacy policy? Please click here for privacy policy.
Are you hiring? We are always looking for quality talent. If you would like to contribute, then please send your cover letter and resume to [email protected].
Do you have a bug bounty program? Yes, we pay for bugs, so contact us for details or visit us at CrowdCurity.com and submit bugs there!
Do you perform off-chain transactions? No we do not. All cryptocurrencies are sent, usually including miner fees, and can be seen on the blockchain for that respective cryptocurrency. This helps secure the network, makes our transactions transparent, provides an easier way to debug and track down coins, and reduces the chance for fraud. An off-chain transaction would be like what Coinbase could do if both users are Coinbase users and they change coins from one email to another, mark it in the database, and Bitcoin is never actually sent from one wallet to another.
Why does my balance reset after refreshing the page or changing cryptocurrencies? The server updates every 60 seconds and the balances you see updating in real-time are performed with Javascript. If you change pages quickly, or choose a new cryptocurrency, then it will look like it is resetting. However nothign is lost, as whatever cryptocurrency it is set at when the server updates will get the past 60 seconds of mining results.
Help! My account was hacked and withdraws are being made? Eobot is a secure site and has never been compromised. If your account was hacked, then you should change your password, turn on 2FA, and turn on email notifications. There are many unscrupulous Bitcoin sites, and most likely, you used the same password on another site. Never re-use passwords!
Do you have any wallpapers? Yes, you can download wallpaper1 or wallpaper2. Feel free to send us your own creations.
What does Eobot stand for? We have heard everything, let us know your favorite, including: Earn Online Bot, Earn Online Bitcoins Online Tool, Earn Online By Our Tech.
Is this legal? We cannot provide legal advice; make sure cryptocurrencies are legal in your jurisdiction before continuing to use Eobot.
Cloud Mining Questions What are the Cloud Mining fees? For electricity and maintenance, we currently charge a fee of 65% for SHA-256 and 65% for Scrypt. These values will change as difficulty increases, exchange rates change, and newer ASICs come online. These fees are better than our competitors, for instance CEX.IO charges $0.105 per GHS, which is a 81% fee! While GAW charges a 96% fee at current prices!
How long are the Cloud Mining rentals and contracts? Prior to October 11 2014, GHS/KHS contracts had no expiration. Old contracts are not affected. New contracts and rentals, mined or purchased after October 11 2014, are now limited in term for 5 years going forward. See your History tab for expiration dates.
Can I sell my Cloud Mining? No, you cannot sell the cloud shares at this time. This is because we own the hardware and do not want to be stuck if everyone decides to sell at once.
Can I buy Cloud Mining with credit card/USD? Yes, but please keep in mind you cannot sell or convert the Cloud Mining.
Can I buy Cloud Mining with cryptocurrency? Yes, deposit the cryptocurrency and then convert it to your choice of Cloud Mining.
What are the maximums/minimums when making a credit card purchase to buy Cloud Mining? The minimum is 1.0 GHS and 10.0 KHS and there is no maximum at this time.
Can I buy a Cloud Mining that mines in Scrypt? You can use the Cloud Mining SHA-256 hashing power to mine other currencies by automatically converting them as you mine, but the earnings will still be tied to SHA-256/Bitcoin difficulty, not Scrypt/Litecoin difficulty.
What is the difference between Cloud Mining SHA-256 and Cloud Mining Scrypt? One is tied to the difficulty in mining SHA-256 cryptocurrency (Bitcoin) and the other is tied to the difficulty in mining Scrypt cryptocurrency (Litecoin). This means that if history is any indication of the future, then the Cloud Mining Scrypt won't decrease as fast as the Cloud Mining SHA-256.
What does 1 instance of Cloud Mining SHA-256 and Cloud Mining Scrypt equal? 1 of Cloud SHA-256 equates to 1.0 GHS of SHA-256 mining power, while 1 of Cloud Scrypt equates to 1 KHS of Scrypt mining power.
Can I change the pool that my Cloud mines on? No, you cannot; this may change in the future.
What hardware is behind the Cloud Mining? The hardware varies from custom ASICs to GPUs. The ASICs are behind the SHA-256 and the GPUs are behind the Scrypt.
Can I RDP (remote desktop) into my Cloud Mining? No, you cannot at this time; we will run the servers for you.
What is the Cloud Mining Pre-Order? These are the same as the other Cloud Mining, but they will start mining on a later date. For instance, a Cloud Mining Pre-Order October 2014 will start mining on October 1, 2014.
Software/Miner Questions Why is it stuck on "initializing...please wait 5 minutes"? We recently changed our Scrypt pool, so this messge will show and the stats and speed won't show under your account. See pool info page for more info.
Why does it show as a trojan/virus? This is a false-positive that many of the popular antivirus programs report. For now you can ignore it, or try another free antivirus, like Microsoft Security Essentials. Hackers use something similar programs to make money off of people's computers, so that is why it shows up as a virus.
Why does Chrome block the download as malicious? This is another false-positive. Simply, go to your Chrome settings, scroll to the bottom and click on "Show Advanced Settings". Go to the Privacy section and uncheck "Enable phishing and malware protection". You will only do this temporarily. Then proceed to download our software. Then return to your privacy settings and recheck Enable Phishing to further protect you.
Do you have a Mac or Linux version? Yes, see the Pool Info under the Account page.
How do I use cgminer? See this English PDF tutorial for cgminer, or Spanish version, created by one of our members, for a simple walk-through.
How can I increase the speed? Important to increase speed: The default cgminer settings do not include hardware specific flags, which you may find here in the Litecoin Mining Hardware Comparison. Failing to use the proper flags can result in performance decreases in excess of 50%.
What do the intensity settings relate to? This is the same as cgminer flag --intensity. Low is 11, normal is none, high is 15, very high is 17, extreme is 19.
Can I use one account for multiple computers on same IP address? Yes, it will add your speed/rates together, you can use as many computers as you want.
Can I connect to the pool manually, through cgminer or bfgminer? Yes, see the Pool Info under the Account page.
Do you use Bitcoin and Litecoin? Yes, we are the easiest miner to use with BTC and LTC and convert on the backend automatically.
What do you use on the backend? We use cgminer, bfgminer, pooler's CPU miner, and a variety of pools.
Can I mine any cryptocurrency? Yes, regardless if you use SHA-256 or Scrypt (BTC vs LTC mode), you can earn and mine any cryptocurrency.
Can I use an ASIC? Yes, simply choose the option and run as GPU mode. Devices that work with bfgminer will work, for instance USB Block Eruptors or Butterfly Labs ASICs. You can also contact us for pool information for other ASICs.
What is the best graphics card/computer to buy? Either use a high end ATI Radeon card, or buy one of the USB Block Eruptor devices on Ebay/Amazon or a similar online store.
What drivers do I need for USB mode? http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
Why doesn't GPU mode work? You may need to download the OpenCL drivers; get them from here: http://developer.nvidia.com/opencl
Where can I get the .NET framework? Try Windows Update, or use Microsoft Web Platform Installer.
Can I use a proxy server? Yes, edit intensity.txt and put the details in there, for example, add "--proxy=http://mycompany-http-proxy:8080"
Where can I download the software? Download from link here
Can I use custom flags/change intensity? Yes, you can put in whatever custom flags/parameters/arguments you want. Edit the "resources/intensity.txt" file. Put in whatever you want, like for GPU mode: "--intensity 12 --shaders 1024" or for CPU mode (number of threads): "-t 32"

Someone please proofread what I have written below, so it can be posted on r/environment and other such subreddits.

Here is the title.
Bitcoin requires a tremendous amount of electricity to be maintain, but there are much more environmentally-friendly, alternative cryptocurrencies. Please demand that merchants accept the environmentally friendly alternatives.
Executive Summary:
Large Bitcoin mining operations are now being constructed in places where they unnecessarily squander the least expensive, renewable hydro-electric and geothermal-electric resources. There are very environmentally-friendly, readily-available, alternative cryptocurrencies such as Blackcoin and NXT that do not pose a threat to these precious renewable resources.
The environmentally unfriendly coins that require a lot of electricity to mine are called Proof of Work (PoW) coins. The environmentally friendly alternatives like Blackcoin and NXT are called Proof of Stake (PoS) coins.
The price spike in bitcoin last fall has led to an arms race to adopt electricity-gobbling, specialized mining equipment in the pursuit of corporate mining profits. They were not required to maintain Bitcoin prior to their invention. Specialized mining equipment for a second class of coins, which are similar to Litecoin, another PoW coin, is about to start shipping. This will lead to another large surge in unnecessary corporate mining operations and greatly increase the electrical demand in the race for corporate mining profits.
You can read the long report below.to find out more about the issue, and you can visit blackcoin and NXT at the links below to find out more about our coins. If you have heard enough and just want to do something quick and simple to support our efforts, visit blackcoin and NXT, click on our subscriber button to show your support, and then watch us take on Bitcoin. While you visit the two subreddits, you can judge for yourself which one you think will succeed.
Hopefully, some respected environmentalist will start campaigns to get merchants that already accept Bitcoin and Litecoin to start accepting the environmentally friendly alternatives.
http://www.reddit.com/blackcoin
http://us.reddit.com/NXT/
Electrical requirement to mine PoW coins:
The Bitcoin, Litecoin, and Dogecoin ledger are maintained by miners who compete against each other to see who can first find the next page for their blockchains. Only the miner that wins the race for each ledger page gets paid in coins.
As a result of this competition and the late 2013 price spike, Bitcoin mining corporate startups are popping up in central Washington State as documented in the first link below to take advantage of the inexpensive, renewable hydro-electricity and in Iceland as documented in the second link below to take advantage of the renewable hydro and geothermal resources. If bitcoin continue to expand, it will unnecessarily eat up more and more of these valuable renewable resources

The next surge in electricity requirement is about to happen:
The mining hardware manufacturers are about to start shipping specialized mining equipment that can only mine the Litecoin and Dogecoin type of PoW coins as documented in the two links below. This new front in the mining arms race will gobble up much more precious renewable electricity in the competitive pursuit of corporate mining profits than is currently required to update the ledgers of these coins.

This specialized equipment is prostituting the original bitcoin promise
The tremendously profitable mining of crypto coins that are competitively produced is unnecessarily prostituting the original concept of their inventor, Satoshi Nakamoto. He envisioned bitcoins as being mined on standard personal computers while preforming other useful tasks. Instead, special computer hardware is being manufactured costing upwards to $10,000 apiece which can perform only one task. These individual units are being racked up in warehouses now.
This specialized equipment was not required for Bitcoin prior to its invention and is not required currently for Litecoin and Dogecoin. However, it is coming anyway producing an unnecessary arm race in the pursuit of corporate profits.
These specialized dev ices are energy inefficient in a second ways.
These specialized devices generate so much heat that they require elaborate energy-intensive cooling system for large operation. One of the most elaborate of these cooling systems is documented in the link below for a Hong Cong corporate mining operation that emerges the energy-wasting equipment in boiling goo to keep it cool. Thus, not only does it take electricity to run the equipment for these large operations, but more to keep it all cool.

PoS coins are the environmentally friendly alternative.
In contrast, the ledger pages of coins like Blackcoin and NXT are generated by stakeholders who cooperate to perform the task which are being done on standard multitasking computers. Many of these computers would be running anyway as originally envisioned by the inventor of the blockchain.
If you have heard enough and just want to do something quick and simple to support our efforts, visit blackcoin and NXT, click on our subscriber button to show your support, and then watch us take on Bitcoin. While you visit the two subreddits, you can judge for yourself which one you think will succeed.
Hopefully, some respected environmentalist will start campaigns to get merchants that already accept Bitcoin and Litecoin to start accepting the environmentally friendly alternatives.
