Check if there's any BCH left in my address

[dazz.]

Hi guys. I'm wondering if there's a way to check if I have any BCH from the BTC hard fork in my old BTC addresses.
Can I simply download the BCH wallet and replace the wallet.dat with the one in my BTC wallet?

Thanks

If you still have the wallet address, you can check the balance on https://blockchair.com/ and select results for BCH
It shows the results for different blockchains, which would also include forks of Bitcoin such as BCH and Bitcoin SV.

You can use this tool to see the forked coins you can claim:

Also, here is a great guide on how to safely claim those coins, written by LoyceV:

Make sure to move all your btc to a new safe wallet before downloading any forkcoin wallet.

Yes... If you have been using Bitcoin Core, then the wallet.dat from that will be compatible with the BCH "Core" wallet.

You'll need to download BitcoinABC or whatever the "core" BCH wallet is these days (given the whole BCHA and BCHN bunfight, it's difficult to know which is the "real" Bitcoin Cash shitcoin )... then put a copy of your Bitcoin Core wallet.dat into the datadir for the BCH wallet app. Then open the BCH app and let it fully sync.

Thanks guys. I had already checked in the BCH block explorer and there is some dough in there.
I'm an idiot. Back when the hard fork happened, I sold all the BCH I had in Poloniex almost immediately, but it didn't even occur to me that there would also be something left int my offline wallet. Lost quite a bit of money, but hey, live to learn I guess

I used Electron Cash to claim my BCH, can’t remember what I used to claim BSV, could have been Coinimi mobile app. Like said above though, make sure you move you bitcoin out of those addresses before you start claiming shitcoins.

I will, thanks again.
I really need to keep up with all this stuff. What a fuck up.

My "favourites":

• Electron Cash for BCH
• Coinomi (Android) for BSV
• Coinomi for BTG
• Electrum-BCD for BCD
• Electrum ABC for BCH-A (note: some websites call BCH BCH-ABC, some call BCH-A BCH-ABC. It doesn't make much sense)

If you have any substantial amount: I wouldn't trust any of those Electrum-clone-wallets, import read-only (import addresses instead of private keys) in a VM and sign the transactions offline.

Quoting myself:

I wrote a very short summary of getting Forkcoins out of multisig, part of this can be used without multisig too.
For splitting Forkcoins and forcing replay protection, I can get you some Forkcoin dust. However, before doing this, I'd love to get $1 worth of pre-fork coins that exist on all 3 chains (BCH/BSV/BCH-A). This can only be created from unsplit coins, which you have. I'm not sure if Electrum adds a locktime, and if it does it might influence replaying transactions. This is one of the things I'd like to test when I have a small amount of unsplit coins.

Note: before doing anything related to Forkcoins: move your Bitcoins to a new wallet so you don't risk them.

Does it make more sense (timewise) to claim all the forks directly on coinomi? Except for BCD (IIRC), you can claim the rest directly with them; you move the private keys less times, make a single sweep, and can even dump everything for BTC at the same place.

PS: think you forgot to mention the wallet for BCH-A

Yes, that's faster. But I prefer to sign transactions offline, and BCH is the most valuable Forkcoin. Coinomi still doesn't let you split BCH-A though, and indeed BCD isn't supported.

Added.

Probably a dumb question, but anyway. Would it be safe enough to just change my wallet passphrase, then claim the forkcoins, and then change it back?

No. The wallet passphrase is only required if you are needing to unlock a given wallet file.

If the attacker has your private keys... they don't need your passphrase at all. By importing your seed/private keys into other (somewhat) untrusted forkcoin wallets to claim these coins... you are potentially exposing your seed/private keys.

This is why you are advised to move your bitcoins to a completely new wallet (with a new seed/private keys)... that way, when you import the old seed/private keys into a forkcoin wallet, there is no chance your BTC (obviously the most valuable) can be stolen... because even if the wallet application turns out to be a scam and sends your seed/private keys to scammers, the scammers will only be able to get the low value forkcoins, as your BTC is no longer being controlled by the stolen seed/keys.

[dazz.]

Gotcha, thanks. Right now I don't have a HDD with enough free space to store another copy of the blockchain. I guess I could create an online address and then later import the private keys into a fresh wallet, but I can't screw this up.

Is at least the BCH wallet safe?

EDIT: Silly me, I can simply create a new wallet locally,  transfer my coins there, and then use the old wallet to claim those forkcoins, right? Sorry to be such a pest, but I need to be 100% positive that I'm not missing something.

Even if you created a new Bitcoin Core wallet, you don't need to download the blockchain again. Alternatively, you could use a lightweight client (electrum) that stores no blockchain data. Whatever you decide to do, the forked coins should be safe if you only move the BTC from address 1 to address 2; doing nothing with the private keys/seed in between

EDIT: Silly me, I can simply create a new wallet locally,  transfer my coins there, and then use the old wallet to claim those forkcoins, right? Sorry to be such a pest, but I need to be 100% positive that I'm not missing something.

You could... but the issue is that you still need to download the forkcoin blockchain if you want to use the old wallet.dat with the forkcoin wallet... (and in the case of BCH or BCHA or BCHN or whatever the hell it's called these days), that is quite a significant amount of data (not quite as big as Bitcoin Core, but it's still a couple of hundred gigs ).

If you create a "new_wallet.dat" in Bitcoin Core, then move all your BTC from your old wallet.dat to an address in "new_wallet.dat"... then you could simply use the dumpwallet or dumpprivkey on the old wallet.dat file to get the private keys you need.

You can then use any of the wallets that LoyceV listed above to import those keys and get the fork coins.

The important part is to move all your BTC to a completely new wallet.dat first... and then start messing about with claiming forkcoins.

OK, so I need to transfer the coins to a new address in a new wallet.dat and pay whatever fees apply, there's no way around that, right?
Sorry, I don't understand why I would need to get the private keys from my old wallet. Could you please elaborate?

EDIT: Is it to import them into those electrum wallets so I don't need to download the other coin's blockchain?

[HCP]

Unfortunately, that is correct.

Fortunately, the network is quite quiet at the moment... transactions with just 5+ sats/byte fees are getting next block confirmation etc. So, you're not having to pay "outrageous" fees right at this point in time

What do you think about Bither wallet?

Sorry, I don't understand why I would need to get the private keys from my old wallet. Could you please elaborate?

Before you can claim the forked coin will need to sweep your old wallet using your private keys or seeds. Thats why you asked to move your BTC to new wallet.

EDIT: Is it to import them into those electrum wallets so I don't need to download the other coin's blockchain?

Yes, Electrum wallet is lite than Bitcoin core but you need to download the wallet from the official site electrum.org and verify the wallet.

Really sorry, but I'm not sure I understand the bolded part. Do you mean I need my private keys to transfer the coins to a new wallet? I plan on doing that with the BTC Core wallet, which would be using my private keys, obviously.
Then I can safely use my (now empty) old wallet to claim the coins, it I got it right.

You need the private keys to be able to "claim" the fork coins... essentially, you need some way to  get those private keys into a forkcoin wallet application.

The options are:

- If there is a compatible [forkcoin wallet], simply use the old wallet file from your Bitcoin wallet and open it with [forkcoin wallet]
or
- Export the private keys from Bitcoin Core, then import them into [forkcoin wallet]
or
- If you have a wallet that supports 12/24 word seeds, you can recreate your wallet in [forkcoin wallet] by restoring a wallet using your 12/24 word seed


You currently have a Bitcoin Core wallet.dat. This does not support 12/24 word seeds, so that option is not available. Instead you can:

NOTE: you should do the following after you have created a new_wallet.dat in Bitcoin Core and moved all your BTC to new_wallet.dat!

Option 1. Install BitcoinABC & BitcoinSV "node" software (like Bitcoin Core, but built for BCH/BSV).

- You will need to download and sync each blockchain for each fork that you want to claim. This will require significant on disk storage space and time.
- Then, using BitcoinABC/BitcoinSV node software, open your (now empty) old wallet.dat and let it rescan
- It will find any/all BCH/BSV that is controlled by the private keys in your old wallet.dat
- Do what you want with the BCH/BSV that you find (send to another wallet, sell on an exchange etc)


Option 2. Install "lightweight" SPV wallets compatible with the forkcoins and import private keys.

- As per LoyceV's message, your options are things like:

• Electron Cash for BCH - https://electroncash.org/
• Coinomi (should do BCH/BSV) - https://www.coinomi.com/en/
• ElectrumSV for BSV - https://electrumsv.io/
• Electrum ABC for BCH-A - https://www.bitcoinabc.org/electrum/

Next, you need to export your private keys from the old wallet.dat. You can do this very easily using the dumpwallet command on the Bitcoin Core console. This will generate a text file that contains ALL your private keys.

Once you have successfully exported your private keys, you then need to import them into the lightweight BCH/BSV wallet that you installed. How you actually achieve this depends on the wallet you're using. Most have a menu option that allow you to "import", or in the case of the Electrum "clones" (ElectronCash + ElectrumABC), when you create the wallet, there is a "Import Addresses or Private keys" option.
