How to claim Bitoin SV from bitcoin core private key

Hi! I would like to know a few precisions on how to get bitcoin SV from an old (pre-bch fork) bitcoin core private key. I was able to successfully get my BCH in electron cash wallet (importing the B-core pvt key). However, I am still unsure on how to do the same procedure using the electrumsv wallet to get the corresponding bitcoin SV on the same machine because of potential conflicts between the 2 wallets. My options are:
A: 1- Send all the BCH fist to a cold hardware wallet (for security), 2- uninstall electron cash wallet. 3- install electrumSV wallet and paste in the same Pvt key I used to get the BCH
B: 1- No need to uninstall electron cash wallet, (keep BCH inside or send it first it does not matter) 2- install electrum wallet and paste in the same Pvt key I used to get the BCH
C?: Any other ideas are welcome, thank you !

Recovering private key of change address from Bitcoin Core

Hello, I am trying to help my mostly Bitcoin-ignorant friend with the following problem:
A long time ago, he mined some BTC using Bitcoin Core client with unecrypted wallet.dat.
Some years later, he added encryption to his client and sent some BTC to someone else ("transaction X"). Then he forgot the password of his wallet.dat.
He had backed up the original (unencrypted) wallet.dat file so I managed to extract private key of his mining address from it and send his funds safely elsewhere.
However, during "transaction X", around 0.7 BTC ended on a new "change address". I cannot access the private key of this "change address" because it was generated after the wallet was encrypted and he forgot the password.
Or is there a way to find this private key, e.g. are the change addresses PKs in Bitcoin Core generated using some non-random derivation algorithm?
I have access to both versions of the wallet.dat file (original unecrypted and later encrypted before "Transaction X")
EDIT: Thanks everyone. The wallet was old (non HD) type so the change address' private key is probably lost forever, unless my friend remembers his password.

Can Bitcoin Core produce script descriptors that contain private keys?

I've been messing around with offline signing and script descriptors. I read somewhere that a script descriptor can contain a private key, which makes me nervous that I will accidentally offload a private key in the descriptor from cold storage.
Can script descriptors store the private key?
Does Bitcoin core create script descriptors that store the private key?
If so, what steps do you take to create such a script descriptor (so that I don't do that.)

Is it safe to import a private key on bitcoin core

Is there any way someone could get access to my wallet if I do this or is it safe?

Could a Hard Fork deliberately leak private keys?

Say for example there was closed source hard fork tomorrow, could that hardfork be designed to deliberately leak your private key when you transact with it?
I'm imagining this as an attack vector against Bitcoin Core, where users want to move or sell their free fork coin and unwittingly expose their Bitcoin Core private keys to the Hard Fork creators.
Is this realistically possible?

My conversion failed and I might have lost 20 BCH somehow

I bought BTC a long time ago and it's lived in a Bitcoin Core wallet.dat file. My read on how to fork properly was to wait until the fork happened, then transfer all my original BTC to a new wallet (which I did by sending a handful of transactions to an Electrum wallet), then after the post-fork BTC was safely associated with a new keypair in a different wallet, and Bitcoin Core showed 0 BTC, that I could use the private keys in that wallet and "Sweep" them with the BCH Electron Wallet. I had 5 Bitcoin Core private keys and swept each into Electron Client. Only one of the Bitcoin Core private keys had anything on it, 50 mBCH, which means I'm missing the VAST majority of my BCH somehow.
I'm currently building a new isolated VM to install Bitcoin ABC on, but the block chain will take about a day to sync, so I'm kind of frantic about there being a missing ~$30k worth of BCH that may or may not still exist while I wait to import an old pre-fork copy of the Bitcoin Core wallet.dat.
Does anyone have any similar experience with moving forward on the fork and running into this problem?
As you can imagine I'm kind of distraught right now until I figure out what the heck happened.
Thanks!

Claiming my BCH/BCC in order to eventually exchange it for BTC, am I doing this right?

Hi Folks,
Took me a while but was not in a hurry, I want to claim and trade my BCH/BCC to BTC, not taking chances (based on my understanding of crypto currency) I did the following.
PC#1) Existing Bitcoin core full node wallet, always running.
PC#2) Created a full node bitcoin ABC wallet, got it fully synced (took a bloody week, disk I/O at 100% there is no good reason for this! I'm sure that can be optimised!). Once fully synced I shut it down. I then copied my wallet.dat file from PC#1 to this PC#2 and restarted bitcoin ABC. My BCH/BCC show up as expected. I shut it down.
PC#3) (my next step, create a new bitcoin core full node wallet) Since my bitcoin core private key is now also in the bitcoin ABC wallet (PC#2) and that I don't feel safe with that, I decided a new bitcoin core wallet with a new private key was in order, I can then transfer my BTC to a new private key.
Does this make sense? did I miss anything?
Any and all remarks will be appreciated.
(BCH, BCC, ABC....consistency at it's best)
Thx!!

I predict that Bitcoin Core will stop advising Bitcoin holders to control their own private keys.

It has always been advised for users to hold their coins in their own wallet - not keep them on an exchange. If you don't control your private keys, you don't actually have Bitcoin. For as long as I have been in this space, that has been the number one rule.
I predict Bitcoin Core will begin distancing themselves from this cardinal rule, or perhaps even belittling it. As Bitcoin inches nearer to mainstream adoption - at the same time as suffering high fees and transaction backlogs - to use Bitcoin is to begin to consider alternatives.

I am searching for an Android Bitcoin Cash Wallet that can import (or sweep) a private key (WIF) from a Bitcoin Core cold storage paper wallet.

SOLVED. The app "Coinomi" did the trick (not import, but sweep, which is ok for the low network fees...)
(btw, also works for BTG)
Any recommendations / tips?
Actually "import" would be preferred over "sweep", but since Tx Fees are so low with BCH, also "sweep" is acceptable for my use-case.
What I mean is entering (or sweeping) my own single private key* (legacy WIF format as we know it from paper wallets**), and NOT entering my own determinsistic 12-word-mnemonic seed.
For the following Bitcoin Core wallets I am aware that they support it - but I am looking for a Bitcoin Cash Wallet that can do the same:
The following Bitcoin Cash wallets cannot do it:
Oh - and I'd like to enter the private key manually via text, not via QR code scan, if possible (because I only have the private key ("5.....") in text form and don't want to convert it to one of those QR code generator online websites, for obvious reasons). (removed, because bitaddress.org used offline serves this purpose to convert priv key (text) to QR code)
PS: If anybody also knows about BTG for the same question, I'd be interested, too, obviously.

Bitcoin Core wallet shows larger balance than sum of all private keys exported to Electrum.

I went through my transaction history and exported the private key for every receiving address I have ever used into Electrum. The resulting balance in Electrum is only about 75% of the balance that Bitcoin Core shows. Is there any way that earlier transactions might not be showing up in my transaction history? I don't have any pending transactions.

I've downloaded all of bitcoin core and sent bitcoin to my address. What do I have to do to set up a mnemonic private key and how do I back it up?

I can't imagine I have to back up the whole blockchain on a second device.. ??

Dumping private key from outdated, un-openable Bitcoin Core

Quick backstory, boiled down: Bought BTC 2 years ago, didn't understand how to use wallets, so sent newly purchased balance to Bitcoin Core (when it was unsynced - and it still is).
Fast forward: Didn't touch it until recently, but now I get an error when opening Bitcoin Core: Error when reading from database, shutting down when trying to open the wallet (to access the console and dump the private key.) I have 0.10 version of Bitcoin Core, but I still have the wallet.dat and address.
TL;DR: screwed up, need help to get back into Bitcoin Core to be able to dump the private key
Thanks in advance!

Sweeping private Key vs. Importing private key from bitcoin core to electrum

So i made a post a few weeks ago, about how my start up disk is full and i cant finish downloading the block chain from bitcoin core onto my computer, and as a result i cant access the BTC that I had already sent to the wallet. So i was told how to transfer the private key from bitcoin core to electrum, but i just want to make sure im choosing the correct option of doing it. I can either make a non seeded wallet with electrum and then import the private key, or i can create a seeded wallet and then "sweep" the contents of my bitcoin core wallet by using the private key... I really dont want to lose this money, and i basically will never be able to use bitcoin core and need to delete the file as soon as possible so i just want to make sure the BTC gets directly transferred to electrum, with out it getting deleted some how. thanks!

Private Keys on Bitcoin Core Wallet

So, I wanted to test the Bitcoin Core Wallet. For this I wanted to get my private key of my wallet. For this end I opened the debugwindow and did walletpassphrase and then I opened op receive, to reveal my public adress. Finally did a dumpprivkey + pubkey in the console. It got me the private key. But everytime I am requesting a new transaction, the public key changes and therefore (this is what I cant understand) the public key.
So how can I manage my private key, when it changes, everytime I want to receive a transaction? Or just tell me where my fault is.

Trezor BIP49 private keys not importing into Bitcoin Core

I used the Mnemonic Code Generator to generate my private keys from the website https://iancoleman.github.io/bip39/. I of course used an offline computer. All my public addresses matched my Trezor addresses. However the private keys do not import into Bitcoin Core using the importprivkey command with the private key at the console. I'm using the new segwit wallet addresses in the Trezor.
What am I doing wrong? Is the website tool faulty?
Please advise. Thank you,

Imported private key from Bitcoin Core - only 1/10th the amount?

I'm new to BCH, so bear with me. I imported my BTC private key to a BCH wallet (in this case, it was 1 BTC) to 'sweep', but my BCH wallet only shows .1021 instead of 1 - is that right?
