Man Recovers 9 year-old Lost Bitcoin Wallet with $400k Using Claude AI

• A Bitcoin wallet containing 5 Bitcoins was successfully recovered after being presumed lost for 9 years.
• The user found the Bitcoin wallet in his old college laptop.
• He used Claude to decrypt the wallet by feeding it old college notes in an attempt to find some patterns between the notes and the password.
• The recovered Bitcoin, which was bought for around $200, is now valued at almost $400k.

How was he able to decrypt the Bitcoin private key?

He didn't. Claude was able to brute-force its entry from the old notes, which provided a possible look at common phrases and alphanumeric combinations the author might have used as a password. Bitcoin’s private key remains unbreakable despite advances in computational power.
