A Bitcoin trader has successfully recovered approximately $400,000 worth of cryptocurrency after losing access to their wallet 11 years ago, using Anthropic's Claude AI to brute-force the forgotten password. The AI reportedly attempted 3.5 trillion password combinations before decrypting an old wallet backup, highlighting both the potential and risks of AI-driven recovery methods in the crypto space.
Live News
In a story emerging from the cryptocurrency community, a Bitcoin trader has regained access to a wallet containing roughly $400,000 in Bitcoin after losing the password more than a decade ago. According to the trader, the password was forgotten after a period of heavy cannabis use—colloquially described as getting "stoned"—which led to the lockout. The wallet had remained inaccessible since approximately 2015.
The recovery effort relied on Anthropic's Claude AI, which the trader employed to generate and test password variations against an encrypted wallet backup. Over an extended period, the bot attempted an estimated 3.5 trillion password combinations before successfully decrypting the file. The trader noted that the AI's ability to process massive combinatorial possibilities was crucial, as manual recovery would have been practically impossible.
The incident underscores a growing trend of using large language models and AI-driven tools for cryptocurrency wallet recovery. While such methods offer hope for those locked out of their digital assets, they also raise questions about security vulnerabilities. The trader, who has not been publicly identified, has reportedly moved the recovered funds to a new wallet with improved security measures.

Professionals factor in recurring trends, such as commodity harvest cycles or fiscal year reporting periods, to optimize entry points and mitigate timing risk.
Key Highlights
- AI-Assisted Recovery: The use of Claude AI to brute-force a forgotten password marks one of the most high-profile instances of AI in cryptocurrency wallet recovery. The bot processed 3.5 trillion password attempts, far exceeding human capability.
- Long-Standing Lockout: The wallet had been inaccessible for 11 years, a period during which Bitcoin's value surged from under $500 to tens of thousands of dollars. The $400,000 recovered reflects the current market valuation.
- Human Error in Crypto: The incident highlights how simple mistakes—like forgetting a password—can lead to significant losses in self-custodied crypto. The trader's use of cannabis was cited as a contributing factor.
- Security Implications: The success of this AI-based recovery method may prompt both individuals and security researchers to reconsider the robustness of wallet encryption. Conversely, it also demonstrates that even strong passwords could potentially be cracked given enough computational power.
- Market Context: The recovery comes amid a broader crypto market recovery, with Bitcoin trading around recent highs. The story adds a human element to the ongoing narrative of lost or inaccessible crypto assets, which some estimates suggest total millions of dollars in value.

Expert Insights
The use of AI for cryptocurrency wallet recovery represents a double-edged sword for the industry, according to cybersecurity and crypto analysts. While it offers a lifeline for individuals who have lost access to their funds—a common problem in the self-custody ecosystem—it also exposes potential vulnerabilities in wallet encryption standards.
Experts caution that while brute-force AI tools may work for certain password patterns, they are not a panacea. The success of this particular recovery depended on the wallet's encryption algorithm and the password's complexity. Most modern wallets use advanced key derivation functions (like PBKDF2 or Argon2) that slow down brute-force attempts significantly. The 3.5 trillion attempts suggest the password was relatively short or used common patterns, making AI-assisted cracking feasible.
From an investment perspective, the story underscores the importance of secure key management. Traders and hodlers are reminded to use hardware wallets, multisignature setups, and robust password managers. Relying solely on memory—especially under the influence of substances—carries substantial risk.
The broader implication for the crypto sector may be increased interest in AI-driven security solutions, both for recovery and for penetration testing. However, regulators could scrutinize such tools if they enable unauthorized access to wallets. For now, the tale serves as a cautionary note: while AI can help reclaim lost assets, it also highlights that no password is entirely safe from sufficient computational effort.
