One of the first facts newcomers learn about Bitcoin is that its creator is pseudonymous — and, on paper at least, a billionaire multiple times over. Close to 1.1 million BTC is widely attributed to Satoshi Nakamoto, yet that figure rests not on a confirmed identity but on a forensic trail pointing to a mining operation rather than a person. The estimate can also swing by more than 200,000 Bitcoin depending on how strictly a particular "fingerprint" test is applied.

That distinction became impossible to ignore when 600 BTC mined in 2010 stirred to life after 16 years of dormancy, triggering speculation that "Satoshi's coins" had awoken.

The coins traced back to 12 long-dormant block rewards that had been mined over four days in March 2010 — a period when every block still carried a 50 BTC reward — and sat untouched until Sept. 5, 2026, when whoever controlled the private keys spent them one by one within half an hour. But moving that roughly $46 million in Bitcoin does not mean the spender was Satoshi.

The blockchain traces coins, not people

On-chain tracker Whale Alert found no connection between the 600 BTC and the stash of Bitcoin's mysterious creator. Movements of coins from that era draw outsized scrutiny because Nakamoto went silent by 2011 and the fortune attributed to him has never moved. Blockchain research firm Bitquery went further, determining that 10 of the 12 blocks did not match the distinctive mining pattern that has come to be associated with Satoshi's mining operation, known as "Patoshi." The two remaining blocks showed only weak matches that could occur by chance, according to Bitquery researcher Gaurav Agrawal.

The rewards were, however, mined by a single machine, and whoever spent them in September controlled the private keys. As Agrawal points out:

"What the chain cannot say is whether the hand in 2026 belongs to the person who ran the machine in 2010."

It is a mystery likely to remain unsolved, since private keys can be inherited, sold, stolen or recovered from an old drive found in a secondhand store. "The chain only records that someone had it," Agrawal notes. The spending transactions used modern wallet software that the 2010 client could not have produced, so "at the very least, the keys were loaded into something new."

The Patoshi pattern behind the fortune

If the blockchain cannot say who owned those early coins, what supports the belief that the 1.1 million BTC belonged to Satoshi? Circumstantial evidence is the best evidence available.

In 2013, researcher Sergio Demian Lerner identified a distinctive fingerprint in Bitcoin's earliest blocks, suggesting one miner operated a machine that behaved differently from the other machines on the network — a pattern traceable across thousands of blocks, which he detailed in a 2013 blog post on Satoshi's fortune. Lerner estimated that the miner had amassed around 1.1 million BTC, and more than a decade later he still stands by his calculations.

" is accurate," he tells Cointelegraph Magazine, "with a disclaimer that the evidence is circumstantial; there is no math proof or direct witness."

The case for connecting Patoshi to Satoshi goes beyond the mining fingerprint. Several early Bitcoin users — including Hal Finney, the recipient of the first Bitcoin transaction sent by Nakamoto, plus Dustin D. Trammell, Nicholas Bohm and Mike Hearn — received transfers that exhibited the Patoshi pattern, Lerner says:

"All those transfers were made from coinbases in the Patoshi pattern: that provides compelling reasons that Patoshi and Satoshi are the same person, although not proof."

Lerner also says the miner appears to have been using specialized mining software rather than the standard client — software that was likely created before Bitcoin launched in January 2009. That makes it "highly improbable" that another miner developed a working specialized setup in the few hours between the Bitcoin v0.1 announcement and the mining of the first block. "Whoever was mining the Patoshi pattern started right at the earliest beginning," he says.

Bitquery rebuilt the fortune from scratch

Thirteen years after Lerner identified Patoshi, Bitquery rebuilt the fingerprint from raw blocks, grading 54,316 blocks from Bitcoin's early era and following every coin through Sept. 1, 2026. The firm published its findings in an investigation into Satoshi Nakamoto's estimated net worth.

Its "highest grade" reconstruction agrees with the public Patoshi list on 99.2% of blocks, and Bitquery also found zero exceptions in a timestamp-ordering test across 5,836 adjacent block pairs. "I don't know of a stronger test for this," Agrawal says.

The analysis does, however, cast some doubt on the famous 1.1 million BTC figure itself, because Bitquery's total varies with how strictly the pattern is applied. "Run strictly, the fingerprint covers just under 0.9 million BTC," Agrawal says, with the "most generous reading" at around 1.17 million.

That is not to say Bitquery disproves Lerner's estimate, but it shows how the size of the Patoshi stash depends on how the mining pattern is interpreted. "The published estimates of 1.0 to 1.13 million sit inside that range, so we did not move the number," Agrawal says.

What links Satoshi to the 1.1 million BTC

According to Agrawal, the claim that "Satoshi owns 1.1 million BTC" is really three claims stacked on top of each other. The claim that the coins came from one machine is supported by strong evidence. The claim that the machine belonged to Satoshi is circumstantial. And the claim that the keys still remain under his control cannot be proved simply because the coins have never moved. According to on-chain analytics platform Arkham, the entity labeled "Satoshi Nakamoto" still ranks as the largest holder of BTC — a hoard equal to roughly 5% of Bitcoin's capped supply of 21 million coins.

Bitquery's work also uncovered a 2010 transaction the firm could not find reported "in any published study." On May 17, 2010, 600 BTC from early mining rewards moved in two transactions about an hour apart. The first, at 22:04 UTC, spent 10 block rewards worth 500 BTC, and the second, at 23:07 UTC, spent another two block rewards worth 100 BTC. Those coins had been mined at different points throughout 2009, including rewards from near both the beginning and the end of Bitcoin's first year.

"It matters, I think," Agrawal says, "because it is the clearest moment where the chain itself, and not a statistical pattern, says these blocks belong together." He calls it "as close as the chain gets" to confirming that blocks from all over 2009 sat in one wallet — "which is what the pattern claims for the whole set."

What is known, then, is that whoever controlled those keys had access to block rewards mined across 2009. What is not known is who was behind them.

Unlike the May 2010 transaction, the 600 BTC that moved this September do not belong to the Patoshi miner, and there is no new evidence connecting them to "Satoshi's" stash. If the Patoshi coins themselves ever move, the transfer will be recorded on the public ledger for every analyst to see. As Agrawal puts it: "Nothing in the math settles it, so we will never be sure."
