I think your only chance for most is to import the private key into the relevant wallets like Bitpie and wait for someone to start mining them again. It could be a wait.

There'll be stuff like Bitcoin Gold and Bitcore and a few others that are alive. The majority are goners but they were born dead anyway.

I don't know, I've never tried it, and can't find a quick answer to your question either.

I can do this for 10% fee, but only for those "main forks". The many smaller forks are barely worth it nowadays, and I just don't have the time to figure them all out.
Also note that the values are much lower now than when I opened this topic. Currently you're looking at around 0.2 BTC.

That's even easier

While I'm at it, I'll get the BTG too. That one shouldn't be too difficult.

Don't just PM your seed phrase words, I'll PM you a bit more complicated instructions.

Nope, I don't have the skills to do that, and most forks are worthless by now anyway.

Now that I'm done, I'll create a very short overview of how I would approach this if I'd have to do it again:

Getting Forkcoins out of multisig
Install Electrum on an offline system, running from a LIVE Linux DVD.
Restore the 2FA wallet by creating a new wallet from your mnemonic, but choose to Disable 2FA.
Click File > Save a copy.
Open this text file in an editor. It'll give you 3 xpubs and 2 xprivs. This is what you need, but keep the xprivs offline!
Install a VM on your online system, install Electron Cash in there. Create a new wallet, select Multi-signature, choose 3 cosigners and 2 signatures. Import the 3 xpubs (NOT the xprivs!). This should give you a read-only wallet with the balance.
Create a legacy Bitcoin address any way you want. Make sure this is secure, preferably offline and air-gapped. Keep this!
Create a transaction from Electron Cash (your online watch-only wallet). Send all funds to your legacy wallet. If all funds exist on all chains (so your Bitcoins were all older than August 1, 2017), the lack of replay transaction means this transaction is also valid for BSV and BCH-A.
Click Preview, copy the transaction. Use a QR-code or USB-stick to copy it to your offline system.
On your offline system, install Electron Cash. Create a new multisig wallet. But this time it should be able to sign transactions, so use the 2 xprivs and the third xpub.
Open the unsigned transaction in your offline Electron Cash, sign it, and copy it again.
Use your online Electron Cash to broadcast the transaction.
Pray a bit, and calm your nerves
Check https://blockchair.com/bitcoin-cash/address/1addy, https://blockchair.com/bitcoin-sv/address/1addy and https://blockchair.com/bitcoin-abc/address/1addy. If all went well, all funds on all chains should have moved from your multisig address to the legacy address on their respective chains.
Get some Forkcoin dust that only exists on one of the chains to ensure replay protection on all chains. If not all Forkcoins moved, you'll need to manually get them out of multisig again.
Use your favourite wallet for each Forkcoin to import the address (read-only) and create an unsigned transaction sending the entire balance (use all inputs on that chain, including the Forkcoin dust for that specific chain) to a new address on that chain. Sign the transaction on an airgapped system, then broadcast it. Repeat this for all Forks, start with the most valuable Forkcoin.
Bitcoin Gold and Bitcoin Diamond have replay protection, you'll need to get them out of multisig the hard way. BCD has a working Linux clone of Electrum, for BTG I used the Windows clone of Electrum using Wine.

Disclaimer: use this at your own risk! Be sure to know what you're doing before doing it. When in doubt, don't do it. And don't hold me responsible, you and only you are responsible for following my advice.

This sounds like a Royal Pain just curious what the current table is seeing if it's worth it
Also is Bither still working see no issues with Bitpie

I might get back to you on that offer looks like 1K less Bitcoin Cash which I did bother with back then regret not doing BTG too
Looks like a correction is happening again so not really worth it until the alt forks move up a bit more with the bull run.

Unlike 2018 it really is a fraction of what it was if it was done closer to the fork well those are shitcoins for you however I'll keep a note in mind though as I do have a few buddies with old ass wallets that might be in need of services as well.

Those are the ones I extract nowadays:
BCH: $400
BSV: $165
BCH-A: $15
BTG: $8
BCD: $5


Thanks thought so Bither looked buggy, most of these forkcoins are worthless so it makes sense
Kind of reminds me of BNB token staking on Binance and getting crappy de-fi tokens from Binance (Paris St Germain Tokens, Football Club Fan Tokens) ... sell

The point is forking results in a lot of crap in the long haul back to BTC.

Most of the links are outdated by now, but I still use Find my coins. I've seen some inaccurate results on this site though.

Blockchair is probably correct.

What's the address?

It shows this:
That's the problem. Findmycoins could (should!) have created a snapshot with all balances the moment each fork happened, but apparently they're checking actual transactions.

Before you claim your Forks and split your coins: Can I buy $1?
