A developer says he may have found a way to recover one of the best-known lost Bitcoin wallets from the early days of the network. The wallet belongs to a user known as “Stone Man” and holds 8,999 Bitcoin, worth about $700 million at current prices.
Important to Know
- Stone Man bought 9,000 Bitcoin in 2010 and lost access to 8,999 BTC.
- A developer claims a new GPU-powered tool may help recover the wallet.
- No one has proved the method works yet, and the Bitcoin has not moved.
Why The Stone Man Wallet Still Gets Attention
A wallet with 8,999 Bitcoin has stayed untouched for almost 16 years. For Bitcoin people, that alone makes the Stone Man story hard to ignore.
Stone Man bought 9,000 BTC in 2010, when Bitcoin software still felt rough and backups were easy to mess up. He used Bitcoin client 0.3.2 from a Linux boot CD. After sending 1 BTC to one of his own addresses, the software created a change address for the remaining 8,999 BTC.
A change address is part of how Bitcoin transactions work. When you spend only part of your Bitcoin, the leftover amount gets sent back to a new address in your wallet. We can think of it like getting change after paying cash.
That normal Bitcoin process caused the problem. When Stone Man shut down the computer, the boot CD wiped the updated wallet.dat file. His backup did not include the new change address. So the 8,999 BTC stayed locked at an address without the saved private key.
A private key works like the master password for a Bitcoin address. Without it, you cannot move the coins.
New Recovery Claim Uses GPU Power
A Reddit user named CompetitiveRough8180 now says he built a tool that may be able to crack the Stone Man wallet.
The tool uses CUDA, a technology that lets graphics cards run huge amounts of calculations at the same time. In normal language, GPUs can test many possible answers quickly, which helps with certain types of password or key searches.
The claim centers on weak entropy in early Bitcoin wallets. Entropy means randomness. Bitcoin wallets need strong randomness to create private keys that no one can guess.
If old Bitcoin software created some keys with weaker randomness than expected, the search area could become smaller. That would not make Bitcoin keys easy to guess, but it could make one narrow recovery attempt less impossible than a normal brute-force attack.
Brute force means trying possible keys until one works. For normal Bitcoin wallets, that idea makes no sense because the number of possible keys is far too large. A flaw in how a key was created would change the math.
Proof Still Comes Down To One Thing
The claim still needs proof. A post about a lost Bitcoin wallet worth about $700 million will always draw attention, but a real recovery needs a verifiable transaction.
Until the 8,999 BTC move, the story stays in the “possible but unproven” category.
Bitcoin private keys are designed to be practically impossible to guess. A recovery chance only exists if the old wallet made the key in a flawed way or left enough clues for a focused search.
So we should separate two ideas. A new recovery method can be technically interesting. A cracked wallet requires proof on-chain, where everyone can see the coins move.
Old Bitcoin Wallets Could Face New Questions
If the tool works, the Stone Man wallet would not be the only story. Many early Bitcoin users lost coins through deleted wallet files, broken hard drives, forgotten passwords, bad backups, and old computer setups.
Millions of Bitcoin may be lost forever. Many of those coins came from the early years, when wallet software was less polished and users often had no clear backup routine.
A working method for some early wallets could therefore raise big questions for old Bitcoin addresses. Still, for now, the Stone Man wallet remains locked, and the developer claim remains unproven.
