He changed the password for his wallet during his college years around 2015 and forgot everything afterwards. 2. He only has one old mnemonic word left at hand, which he couldn't solve after trying several trillion passwords with btcrecover+before. 3. In the end, the dead horse became the living horse doctor and uploaded all the files of the old computer to Claude. After Claude scans, he accurately finds a dusty old wallet.dat file (which is the version before changing the password). 5. Use the old mnemonic he retrieved (actually the second password in the sentence "lol420fuck thePOLICE! *:") to successfully decrypt locally and restore the private key. On May 13th, all 5 BTC were scanned out and the transaction at address 14VJySbsKraEJbtwk9ivnr1fXs6QuofuE6 was publicly available on the blockchain. Claude even helped him correct missing or scrambled words in his mnemonic, debug the btcrecover tool, and finally directly output "PRIMATE KEYS DECRYPTED! WE GOT IT!!!" This is entirely due to AI's powerful archive analysis and logical reasoning ability, which reassembles old backups that humans themselves have forgotten. It's not about 'AI cracking Bitcoin', but helping him retrieve the wallet he locked with his own hands back then
