In May 2026, a man known on X as @cprkrn had a problem the Archive knows well: a Bitcoin wallet, 5 BTC inside, locked for years behind a password he no longer had. He did what a technical person does. He rented GPU time on Vast.ai, pointed btcrecover at the wallet, and let it run. Eight weeks. Roughly 3.5 trillion password combinations. Total spend: about fifteen dollars, which is excellent value for trillions of anything. Result: nothing.
Then he tried something less heroic. He dumped the entire contents of his old college computer into Claude — the AI assistant — and asked for help.
The AI did not attack the wallet. It read the files. And in that pile of forgotten coursework and downloads, it found something its owner had missed for years: a wallet backup file, dated December 2019, containing the same private keys. That backup was encrypted too — with a password he had written in a notebook all along: lol420fuckthePOLICE!*:). The Bureau reproduces the password verbatim because the historical record matters, and because it may be the most 2019 string ever committed to paper.
A note on accuracy, because the headlines got this wrong: the viral version of this story said an AI “cracked” a Bitcoin wallet. It did not crack anything. CoinDesk debunked that framing directly. No encryption was broken, no key was conjured — the machine simply read everything, with a patience no human has, and noticed what was already there. That distinction is the whole story. The coins were never lost. The map to them was, and it was in the house the entire time.
See also: the time someone hacked time. The Archive's other great recovery, from 2024: hardware hacker Joe Grand and a collaborator recovered 43.6 BTC for a man locked out since 2013. The wallet's 20-character password had been generated by an old version of RoboForm — whose “random” passwords, it turned out, were seeded from the computer's clock. They reverse-engineered the generator, wound it back, and regenerated the exact password it had produced at 4:10:40 PM GMT on 15 May 2013. The randomness was the fiction; the time was real.
Disclosure, in the interest of the record: this website is built with Claude. The Bureau is biased. The number above is still correct.
The Bureau's finding: RECOVERED — the rare file in this Archive with a happy ending. The lesson is unglamorous: before you price your regret, search your old backups. Then come back. We'll still be here.
