I re-read your initial post as I poorly remembered the premisses. Whatever you did, if you can't find your private key(s) creation recipe or wallet storing your keys, I don't know how to proceed without it.


What's the purpose of this? Looks to me like you're just guessing some random dormant public address from 2010 with a conveniently high amount of coins. The history of the initial funding of this address doesn't look much like what you're talking about all the time.

I would summarize the situation like this:

• you barely have any useful documentation or simply can't find it about what you did in 2010
• it seems you don't even know the public address(es) where your coins sit, it they exist
• no backups, no computer from that time anymore, just vague memories
• if you had Bitcoins, maybe even a substantial number, you certainly didn't treat them "well" because: where's your wallet, your public addresses at least? Where are all details to recover it or pull it from reasonable backups?

I might've missed something, but that's not a promissing starting point. And even if you find this USB thumbdrive, it could be difficult to read something off it, when it hasn't been used for more than a decade. The cheap USB shit doesn't get the premium flash chips, though my assumption may just be a bit biased that you used cheap USB thumbdrives. Apparently it wasn't stored in a way to reliably retrieve it. Flash storage isn't made to reliably hold its data for decades.
