A Bitcoin trader who changed their wallet password while intoxicated 11 years ago finally recovered access using Claude AI, retrieving approximately $400,000 worth of cryptocurrency. The user, known as cprkrn, had been attempting to crack their encrypted wallet containing 5 BTC for over a decade without success.

After discovering an old mnemonic seed phrase in a college notebook, cprkrn uploaded their entire computer archive to the AI assistant. Claude identified a December 2019 backup wallet file and uncovered a critical bug in how passwords were being combined during brute-force attempts with the open-source btcrecover tool. With the configuration error fixed, the AI successfully decrypted the private keys after testing 3.5 trillion password combinations.

This recovery showcases how modern AI tools can assist with complex technical problems that stump traditional methods. Early Bitcoin wallets often mixed HD and non-HD keys, requiring password-protected files that seed phrases alone couldn't recover. The case demonstrates practical applications of AI in digital forensics and cryptocurrency recovery.

The successful retrieval represents more than just personal fortune—it illustrates how AI assistance can solve problems that would have taken researchers months to crack manually, potentially saving countless hours in digital asset recovery efforts.
