Claude AI Unlocks $320,000 in Bitcoin Forgotten for a Decade

Key Highlights

• Pseudonymous user Cprkrn successfully retrieved 5 Bitcoin valued at approximately $320,000 with assistance from Anthropic’s Claude AI
• The Bitcoin wallet remained inactive since the beginning of 2015 following a forgotten password change
• Claude analyzed more than 1GB of information spanning various devices, storage drives, and email platforms
• More than 3.5 trillion password combinations were attempted before a seed phrase discovered in an old college notebook provided access
• The entire recovery operation required only $15 worth of AI computational resources

An anonymous cryptocurrency holder going by the username Cprkrn on X has shared how he successfully regained access to five Bitcoin—currently valued at around $320,000—by leveraging Anthropic’s artificial intelligence assistant Claude to unlock a wallet that had remained inaccessible for over ten years.

The Bitcoin holdings had remained dormant since the start of 2015. According to Cprkrn, the lockout began when he modified his password on blockchain.info and subsequently forgot what he had changed it to. He had generated sophisticated passwords and was unable to remember the updated credentials.

He spent eight weeks attempting to forcefully regain entry. With Claude’s assistance, he tested approximately 34 billion password variations using BTCRecover, an open-source wallet recovery application, combined with Python programming. Unfortunately, none proved successful.

Claude subsequently employed Hashcat, a specialized password recovery tool, to evaluate an additional 3.4 trillion password possibilities. This approach also yielded no results. The complete operation cost merely $15 in AI processing fees, based on a report generated by Claude.

In a last-ditch effort, Cprkrn compiled old notebooks from his college days and retrieved a laptop he had previously used, feeding all the information to Claude. Altogether, Claude processed over one gigabyte of information, examining two Mac systems, two external storage devices, an Apple Notes data export, iCloud Mail archives, a Gmail account, and X direct messages.

The Breakthrough That Restored Access

Claude discovered a wallet backup document on his former college laptop with a timestamp from December 2019. By utilizing a mnemonic phrase located in one of his old notebooks, Cprkrn successfully decrypted the backup and retrieved the wallet’s seed phrase.

On-chain evidence corroborates the account. Transaction records from Blockchain.com indicate roughly 5 Bitcoin were transferred from wallet address “14VJy…ofuE6” through five separate transactions on May 13, 2026. The cryptocurrency had remained stationary since early 2015.

The account gained rapid traction across social platforms, attracting commentary from prominent cryptocurrency personalities such as Nic Carter, Laura Shin, and Jesse Pollak.

However, not everyone agreed with how the recovery was portrayed. Certain members of the cryptocurrency community argued that Cprkrn exaggerated Claude’s contribution. A Reddit user named MeteorSwarmGallifrey commented that Claude “didn’t do anything other than search his files” and that nothing “groundbreaking” had taken place.

The Broader Issue of Inaccessible Bitcoin

This successful recovery highlights the extensive problem of permanently inaccessible Bitcoin. Industry analysts estimate that between 2.3 million and 4 million Bitcoin are lost or unreachable, representing approximately 11% to 19% of the cryptocurrency’s total supply. Specialized companies have emerged specifically to assist individuals in attempting to recover lost digital assets.

This situation differs from cases such as James Howell’s, who as of 2025 continued pursuing efforts to retrieve a hard drive containing thousands of Bitcoin from a waste disposal site.
