getting private key from mined BTC for hard fork

[sdub01]

Okay, long story short i discovered a wallet where I had mined some BTC back many years ago.

I am now working to get the private keys out of MINED wallet. 

When I signed up (many years ago, 2010) I got 5 BTC for just signing up.  Yes, you can all hate me. 

I was able to extract the private key in bitcoin core-qt and thru the console get the private key and import it into exodus wallet. (from the btc that was sent to me)

Transaction log showing the 50 BTC.      (I had an extremely old wallet, and sent some to myself which may have created new addresses)

When I do this for the other amount of BTC that I mined, I get this error.

Is there another wallet I should try.  When I extracted the private key from the "Received transaction" it worked fine to claim it in exodus

Many thanks, and all that.

What forks are you trying to claim?

You might have to use different wallet software for different forks if exodus won't work unless you can find another wallet that supports the forks (but we'd need to know what forks you're after).

First of all, I am not convinced what you extracted from a transaction, I kinda doubt it's actual private key, but I am not that technical so I won't insist on this.

I want to tell something else: if you've spent long ago those bitcoins, much earlier than the moment of the fork(s), you will have nothing to claim, since the coins are already spent. Fork coins can be claimed only if you had bitcoins at the address in the moment of forking. So there's a good chance your effort is for nothing.

Thanks. Seriously, to both of you.   Long day so I can re-write this tomorrow if it is not clear.

Bitcoin cash
bitcoin gold
bitcoin SV

Those are what I am after.

There are 2 different wallets.

1 with 5 BTC I got from signing up with bitcoin core-qt in 2010 (yes I am lucky)
and 50 BTC I got from signing up with bitcoin core-qt in 2010 that I MINED.


Okay, let me clarify to NeuroticFish.

I got the transaction ID from the 5 coins I got when I signed up at Bitcoin Core QT back in 2010.  I also had dumb luck and mined 50 BTC.

I went into bitcoin core-qt transaction log, grabbed the info, went to the console, and did a dump of the private key.  I then was able to move 5 bit coin cash into Exodus
I was also able to to do  the same for gold, but not Bitcoin SV

I get this error when I get the private key from the "mined coins" (back from 2010)
for bitcoin cash, and bitcoin gold, and then this error for bitcoin SV

bitcoin cash  https://i.imgur.com/utCXWSx.png    - Only pubkeyhash inputs supported right now
bitcoin gold https://i.imgur.com/utCXWSx.png     Only pubkeyhash inputs supported right now   SAME error as above

bitcoin SV   https://i.imgur.com/rYQb1Vf.png    SEEMS positive that I just need to wait until I have some BSV to pay for the transfer?

If I should use another wallet, please advise.

Thank you.


There are 50 of each of those I can claim. 

I had the bitcoin address since 2010.

Having an empty Bitcoin address doesn't do you any good. LoyceV will find your address from the screenshot tomorrow and check when you moved your Bitcoin.

Thank you @ LoyceMobile

okay, I sent 50 btc on 8/30/2021, fyi.  
sent 5 btc on 1/1 (as a test to myself to make sure I was not tripping)  LOL

As I discovered this on an old hard drive from a move I made.  I thought I may have 5 BTC on it.

I've done very well, and don't mean to be greedy, but if there is 50 btc of gold/cash out there I might as well...

You're forgetting BCD and eCash. Those 2 are also worth it.
But, IMPORTANT: BCH, BSV and eCash don't have replay protection. Meaning: if you send one of them to an exchange without taking precautions, you may lose the other ones. See LoyceV's Bitcoin Fork claiming guide (and service). The price-information is large outdated, other information is still valid.

I've never used "Excodus" so can't give you details there.

From your screenshots:
50 BTC moved on January 8, 2021.
5 BTC moved on January 5, 2021.
5 BCH moved on April 18, 2022. In the same transaction, BCH and eCash moved too. That's because there is no replay protection between those chains. Depending on where you send it, you may still be able to recover them. DO NOT do the same thing to the 50 BTC

FWIW: Sending 50 Bitcoin to a hot wallet is crazy risky.

I believe the problem is that your coinbase transaction is a pay-to-pubkey (P2PK) transaction (which was common very early on) and not a pay-to-pubkeyhash (P2PKH) transaction. That kind of output is no longer used and perhaps the wallet software does not know how to handle it. You might try other wallets. The reference clients will probably be able to handle it.
