<a href="https://pricpr.com/btc-usd/">Bitcoiner</a> Dumps Old Computer Files Into Claude AI, Recovers 5 <a href="https://investment-policy.com/btc-usd/">BTC</a> Lost Since 2015

A Bitcoin user on X, known as @cprkrn, successfully recovered around 5 BTC – worth between $400,000 and $500,000 – from a wallet he hadn’t been able to access for over 11 years. He attributes this success to Anthropic’s Claude AI, which solved a difficult technical issue that had stumped all previous efforts.

  • Key Takeaways:

  • X user @cprkrn recovered roughly 5 BTC worth up to $500K on May 13, 2026, using Anthropic’s Claude AI.
  • Claude fixed a btcrecover bug to decrypt a legacy P2PKH wallet locked since 2014 or 2015.
  • The recovery shows Claude can handle niche technical tasks, raising new hope for holders with old wallets.

Bitcoiner Recovers 5 BTC Worth $500K From 11-Year-Locked Wallet Using Claude AI

The wallet, tied to address 14VJySbsKraEJbtwk9ivnr1fXs6QuofuE6, had been inaccessible since roughly 2014 or 2015. While in college, @cprkrn changed the wallet’s password while intoxicated and forgot the new one. He still had an old mnemonic, “lol420fu**thePOLICE!*:)”, but it no longer opened the current wallet file.

He spent roughly $250 on professional recovery attempts over the years and tried what he described as “like 7 trillion passwords” before giving up on conventional methods. He waited until bitcoin crossed $100,000 to seriously attempt recovery again. By May 13, 2026, the price had pulled back to the $80,000 to $82,000 range, but the funds were still worth pursuing.

As an analyst, I observed a very direct approach to the problem. The user uploaded everything from an old college computer – files, notes, and backups – directly into Claude. The AI was then able to pinpoint an older wallet file, one that existed before a password change, and successfully determined the reason the original mnemonic phrase wasn’t working with the current wallet.

The technical problem came down to how the password was being processed. The btcrecover tool, a widely used open-source bitcoin wallet recovery utility, was concatenating a shared key with the password in an incorrect order. Claude identified the bug, corrected the decryption logic, ran the process, and extracted the private keys in Wallet Import Format.

Screenshot of Claude’s response shared on X.

The recovered keys matched the target address. Claude’s output, which @cprkrn screenshotted and posted to X, read: “ PRIVATE KEYS DECRYPTED! WE GOT IT!!! THE 5 BTC IS YOURS!” The wallet app screenshot that followed showed an imported legacy P2PKH wallet with the full 5 BTC balance and pending outbound transactions.

In a follow-up post, @cprkrn suggested that others facing the same issue simply upload all their computer and notebook files to Claude, summarizing their approach.

According to @cprkrn, this was a final attempt after spending months searching through archived files. He jokingly described the process as: first, download Claude, then upload everything you have and hope for the best.

The X thread drew more than 414,000 views and approximately 1,900 likes within hours. Responses came from across the crypto community, including Nic Carter, Jesse Pollak, Laura Shin, and @bitcoinarchive. Some called it a lifesaver. A smaller number raised questions about the security implications of AI systems working with encrypted wallet files, though the recovery relied on the user already possessing the correct, older password.

What Claude did was not a brute-force attack. It parsed files, understood the structure of legacy wallet software, debugged an existing tool, and ran the corrected process. The wallet format involved was P2PKH, a legacy type common in early bitcoin use before 2015.

A user named @cprkrn closed the discussion by expressing gratitude to Anthropic and its CEO, Dario Amodei, even jokingly saying he planned to name his child after Amodei.

The wallet had last been publicly referenced by @cprkrn in August 2023, when he lamented the locked funds on the same address. The funds he received on April 1, 2015, totaling 5 BTC, sat untouched until they were swept out the same day the recovery was completed.
