Hi everyone.
A client of mine brought me an interesting case. He claims to have mined bitcoins in 2009.
He brought a backup of files that has its creation date of 2009 which made me investigate the case better, because in thesis could be true.
Sorry, I had posted a wrong image, updated now!https://prnt.sc/2690dbkI installed a version of the old Bitcoin Core that it owns and when opening the program I came across a very large amount of BTC and with information that it had actually mined those blocks.
But when synchronizing with the network, at one point the wallet was emptied, which led me to think of a number of things that could have happened so that those BTC were no longer in your wallet.
One is that he really could have mining but when the consensus was applied, another block had been forged with a smaller nounce which would disqualify him from ownership of the reward.
And so, as the app is synchronized, over the years, the BTC that supposedly existed in your wallet are claimed by legitimate miners who have validated your property and with the spread of the blocks the rewards have been sent to the wallets of their respective owners.
When the timing is finalized, when checking the addresses of the wallets that are in the application and the transactions, I come across 4 addresses of which only one had movement and a very low value and the balance of the wallet in 0.00 BTC.
Even so I decided to post here on the forum, so that with your help, suddenly I can identify what is actually happening and if by chance it really is the holder of the balance, as this could be recovered, because I confess that several possibilities comes to mind, but I am quite confused.
If anyone can help me, I am grateful and wish God to bless us all!
