The pioneers of bitcoin sometimes carry around some rather embarrassing digital pans. Some earned their BTC by playing, tinkering or testing unglamorous services. At the time, no one stored these virtual crumbs like an ingot in a safe. Then forgetfulness, bad luck or an old hard drive transformed these absurd tokens into a modern treasure hunt.
In brief
- Claude helped Cprkrn find five bitcoins blocked since 2015 in an old wallet.
- AI didn't break Bitcoin, but sorted old files and linked the right clues.
- The recovered wallet was worth approximately $397,000 to $400,000 depending on available sources.
- The case reignites the debate on the millions of dormant, lost or potentially recoverable BTC.
Claude finds a bitcoin wallet buried under eleven years of digital dust
This story contrasts with that of James Howells, the unfortunate computer scientist who lost his 8,000 BTC in a British landfill. Cprkrn, pseudonymous user X, claims to have recovered 5 bitcoins blocked since 2015. The jackpot was around $397,000 to $400,000, according to estimates reported by several media outlets.
First, the story looks like a forum legend, with old Mac, forgotten notebook and ghost wallet file. Then blockchain data shows that the address starting with 14VJyS moved on May 13, after more than eleven years of silence.
Cprkrn says he searched for a long time, trying trillions of combinations. His cry of victory over X ignited the powder:
[…] CLAUDE JUST CRACKED THIS STUFF. THANK YOU @AnthropicAI THANK YOU @DarioAmodei I WILL GIVE MY CHILD YOUR NAME.

However, Claude did not rob Bitcoin. Above all, the AI followed the right footsteps in a personal mess.
AI Plays Bloodhound, But Doesn't Break Bitcoin's Vault
Nuance deserves a scalpel, not a marketing hammer. Claude did not break Bitcoin's encryption, nor change the rules of seed sentences. The AI reportedly searched more than a gigabyte of data: two Macs, two external drives, Apple Notes, iCloud Mail, Gmail and X messages.
She then allegedly spotted an old wallet file from December 2019, prior to the password change.
THE comment from VC Intern coldly summarizes the case:
Claude didn't break any encryption or brute-force anything. The guy poured his entire old college hard drive into it. Claude found the forgotten wallet file, associated it with the seed phrase he already had, then performed the btcrecover logic perfectly.

Then, Claude would have helped to correct a detail between sharedKey and password in btcrecover. The lock was less mathematical than human.
Lost BTC could awaken a new recovery industry
This case stirs up an old fear of the bitcoin market: lost coins may not always be dead. The estimates cited range between 2.3 and 4 million BTC permanently inaccessible.
Glassnode also mentions more than 7 million dormant coins for years. Fidelity even indicated that more than 566 BTC per day fell into the “old” category, compared to 450 BTC mined daily since halving 2024.
Now, AI is primarily changing the cost curve. Cprkrn would have spent around 15 dollars with Claude, after professional tests billed nearly 250 dollars per failure. The recovery wallet could therefore move from private detective to neural “search engine”.
However, the trap remains venomous. Sending wallet files, seeds or private keys to a cloud AI can expose funds.
The numbers that wake up key hunters
- The bitcoin wallet had remained inactive since 2015;
- BTC price currently reaches $78,985;
- Claude would have cost about $15 worth of calculations;
- Between 2.3 and 4 million BTC would be lost;
- More than 7 million bitcoins have been lying dormant for a long time.
The next thrill doesn't just come from forgotten passwords anymore. A researcher cracked a 15-bit elliptical key with a public quantum computer, winning 1 bitcoin. This breakthrough, 512 times more powerful than the previous record, is already freezing poorly prepared crypto coffers.
