Nearly 1.1 million Bitcoin is widely attributed to Bitcoin's pseudonymous creator Satoshi Nakamoto, but the figure rests on a forensic trail identifying a mining operation rather than a person — and new analysis suggests the estimate could vary by more than 200,000 BTC depending on how strictly a distinctive "fingerprint" test is applied.
The question gained renewed attention after 600 BTC mined in 2010 moved in September, sparking speculation that Satoshi's dormant coins had awakened. Onchain tracker Whale Alert reported no connection between those 600 BTC and the coins widely associated with Nakamoto. Blockchain research firm Bitquery found that 10 of the 12 blocks involved did not match the mining pattern associated with Satoshi, known as "Patoshi," while the remaining two showed only weak matches that could occur by chance, according to Bitquery researcher Gaurav Agrawal.
The coins originated from 12 long-dormant block rewards mined over four days in March 2010 and remained untouched until Sept. 5, when someone controlling the private keys spent them one by one within half an hour. However, spending the approximately $46 million in Bitcoin does not establish the spender is Satoshi. Blockchain technology traces coins, not people. The transactions used modern wallet software that the 2010 client could not have produced, meaning the keys were loaded into new software at some point — but who controlled them remains unknown. Private keys can be inherited, sold, stolen, or recovered from old hardware.
The case for connecting the Patoshi pattern to Satoshi dates back to 2013, when researcher Sergio Demian Lerner identified a distinctive fingerprint in Bitcoin's earliest blocks suggesting one miner operated a machine differently from the rest of the network. Lerner estimated the miner had amassed around 1.1 million BTC and still stands by his calculations. The circumstantial case extends beyond the mining fingerprint: several early Bitcoin users, including Hal Finney, Dustin D. Trammell, Nicholas Bohm, and Mike Hearn, received transfers from coinbases exhibiting the Patoshi pattern. Lerner also noted the miner appeared to be using specialized mining software rather than the standard client, likely created before Bitcoin launched — making it "highly improbable" that another miner developed a working specialized setup in the few hours between Bitcoin v0.1's announcement and the first block being mined.
Thirteen years after Lerner's identification, Bitquery rebuilt the fingerprint from raw blocks, grading 54,316 blocks from Bitcoin's early era and following every coin through Sept. 1, 2026. Their highest-grade reconstruction agreed with the public Patoshi list on 99.2% of blocks, with zero exceptions in a timestamp-ordering test across 5,836 adjacent block pairs. "I don't know of a stronger test for this," Agrawal said.
But Bitquery's analysis cast doubt on the precise 1.1 million BTC figure. Running the fingerprint strictly covers just under 0.9 million BTC, while the most generous reading reaches around 1.17 million. Published estimates of 1.0 to 1.13 million sit inside that range, Agrawal confirmed.
Agrawal described the claim that Satoshi owns 1.1 million BTC as three stacked claims: that the coins came from one machine is supported by strong evidence; that the machine belonged to Satoshi is circumstantial; and that the keys remain under his control cannot be proved because the coins have never moved. Bitquery also discovered an unreported 2010 transaction on May 17, when 600 BTC from early mining rewards moved in two transactions about an hour apart — 10 block rewards worth 500 BTC at 22:04 UTC, followed by two rewards worth 100 BTC at 23:07 UTC. Those coins had been mined at different points throughout 2009. Agrawal called it "the clearest moment where the chain itself, and not a statistical pattern, says these blocks belong together" — but unlike the May 2010 transaction, the September movement does not belong to the Patoshi miner, and no new evidence connects it to Satoshi's stash.
"Nothing in the math settles it, so we will never be sure," Agrawal concluded.
