An X thread claiming Anthropic’s Claude AI helped recover a long-lost Bitcoin wallet worth roughly $400,000 went viral on Wednesday, drawing millions of views.
The posts were shared by a pseudonymous X user, “Cprkrn,” who said Claude helped unlock a Bitcoin wallet containing 5 BTC that had reportedly been inaccessible for nearly nine years. In one post, Cprkrn wrote: “Holy fucking shit OMG Claude just cracked this shit,” tagging Anthropic and CEO Dario Amodei.
Cprkrn also shared an earlier post from August 2023, suggesting the wallet had been “locked” since 2015. Blockchain data cited in the thread indicated the wallet had not moved funds since 2015 until the recent recovery activity.
While screenshots shared on X did not provide evidence that Claude bypassed or broke Bitcoin’s cryptography, they appeared to show the AI assisting with analysis of encrypted wallet files and password-recovery workflows. According to the thread, Cprkrn attempted recovery using tools including btcrecover and Hashcat—software commonly used to test password combinations against encrypted data—without success.
In the account described by Cprkrn, the breakthrough came after uploading files from an old college computer into Claude. The posts said Claude helped identify a file associated with a mnemonic phrase found in a notebook, which then enabled decryption of an older wallet file. Cprkrn wrote: “It found an OLD wallet file that the mnemonic successfully decrypted.”
The thread generated more than 6 million views as users discussed whether large language models could assist with recovery tasks involving encrypted files and forgotten passwords.
Wallet recovery experts cited in the coverage said it is difficult to determine how much of the outcome should be attributed to Claude versus other inputs such as the wallet file, the mnemonic phrase, and historical information needed to reconstruct a password the user already possessed. One expert told Decrypt that Claude’s likely role was “sorting through large amounts of historical data and identifying clues tied to older wallet credentials or password formats,” describing the work as more akin to forensics sorting than password cracking.
The claims also drew skepticism on Reddit, where some users argued the viral posts overstated Claude’s role. One commenter wrote that “Claude didn't do anything other than search his files,” adding that the headline was “vague enough to mislead about Claude’s role.” Another said the situation “isn't revolutionary” and “just reinforces their pre-existing laziness.”
The discussion comes as interest in Claude’s ability to handle complex analysis has intensified following the launch of Anthropic’s Claude Mythos model last month. Anthropic said the model can identify software vulnerabilities and autonomously complete advanced security tasks.
Cprkrn did not respond to a request for comment by Decrypt.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
