TLDR
- A cryptocurrency holder identified as Cprkrn successfully retrieved 5 Bitcoin valued at approximately $320,000 with assistance from Anthropic’s Claude AI
- The digital 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
- Approximately 3.5 trillion password combinations were evaluated before a seed phrase discovered in an old college notebook provided access
- The entire recovery operation required only $15 worth of AI processing power
A user operating under the pseudonym Cprkrn on X has reported successfully retrieving five Bitcoin valued at approximately $320,000 by leveraging Anthropic’s artificial intelligence assistant Claude to restore access to a cryptocurrency wallet that had been inaccessible for over ten years.
The digital wallet remained dormant since the early months of 2015. According to Cprkrn, the issue originated when he modified his password on blockchain.info and subsequently forgot the updated credentials. He had established intricate passwords and simply couldn’t remember the new one he had created.
For two months, he attempted to force his way back into the account. Claude assisted him in evaluating approximately 34 billion password combinations utilizing BTCRecover, an open-source recovery application, along with the Python programming language. Unfortunately, none proved successful.
Claude subsequently employed a password-breaking utility known as Hashcat to examine an additional 3.4 trillion password possibilities. This approach also came up empty. The complete operation cost merely $15 in AI computational resources, based on a report that Claude generated.
As a last-ditch effort, Cprkrn compiled old notebooks from his college days and a laptop from years past and provided the information to Claude. Altogether, Claude examined over one gigabyte of information, including two Mac computers, two external storage devices, an Apple Notes export, iCloud Mail, a Gmail account, and X direct messages.
How the Wallet Was Finally Unlocked
[[LINK_START_0]]Claude[[LINK_END_0]] discovered a wallet backup file stored on his former college computer with a timestamp of December 2019. Utilizing a mnemonic phrase from one of his physical notebooks, Cprkrn successfully decrypted the file and retrieved the seed phrase necessary for wallet access.
Blockchain transaction records corroborate the account. Information from Blockchain.com indicates that 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 rapidly gained traction across social media platforms, capturing the interest of prominent cryptocurrency personalities including Nic Carter, Laura Shin, and Jesse Pollak.
However, not everyone found the narrative compelling. Several members of the crypto community argued that Cprkrn exaggerated Claude’s contribution. A Reddit user named MeteorSwarmGallifrey stated that Claude “didn’t do anything other than search his files” and that nothing “groundbreaking” had taken place.
Lost Bitcoin Is a Widespread Problem
The successful recovery highlights the significant issue of how much Bitcoin remains permanently locked away. Industry analysts estimate that between 2.3 million and 4 million Bitcoin are lost or unreachable, representing approximately 11% to 19% of the total Bitcoin supply. Multiple companies have been established specifically to assist individuals attempting to recover lost cryptocurrency.
This situation differs from cases like James Howell’s, who as of 2025 was still attempting to locate a hard drive containing thousands of Bitcoin buried in a landfill.
Cprkrn himself acknowledged that he “would’ve been too dumb to figure it out” without Claude’s assistance.
