A bitcoin holder known on X as @cprkrn recovered approximately 5 BTC, valued between $400,000 and $500,000, from a wallet he had been locked out of for more than 11 years, crediting Anthropic’s Claude AI with solving a technical problem that had resisted every other attempt. Bitcoiner Dumps Old Computer Files Into Claude AI, Recovers 5 BTC Lost Since 2015 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. His approach was direct. He uploaded the full contents of his old college computer, including files, notebooks, and backups, into Claude. The AI located an older wallet file that predated the password change and identified why the mnemonic no longer worked on the current file. 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. 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. “Just mega dump all of your computers and notebooks into Claude,” @cprkrn wrote in a follow-up post, summarizing the method for others in similar situations. @cprkrn described the process as a last-ditch effort after months of digging through old files. In a separate post he added, “Step 1. Download Claude. Step 2. Mega dump all of your information and pray.” 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. @cprkrn closed the thread by thanking Anthropic and its CEO, Dario Amodei, directly. “Naming my kid after you,” he wrote. 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.
