For years, one of the most persistent claims in Bitcoin history has been that Satoshi Nakamoto controls 1 million BTC. The estimate became deeply embedded in crypto discourse because it implied that Bitcoin’s pseudonymous creator held just under 5% of the total supply, while never spending those coins. That assumption has influenced everything from discussions about coin distribution to theories about dormant supply and market risk.
A later analysis by BitMEX Research, however, cast doubt on that familiar figure. Drawing heavily from earlier work by Sergio Lerner, the research argued that while there is meaningful evidence for a dominant miner operating in Bitcoin’s earliest days, the confidence around the “1 million BTC” estimate may have been overstated. In BitMEX Research’s view, the available evidence may support a lower number, with 600,000 to 700,000 BTC presented as a more plausible estimate.
How the 1 Million BTC Figure Became Canon
The original estimate traces back to a 2013 analysis by Sergio Lerner, who examined patterns in early Bitcoin block production. His work suggested that a large cluster of blocks may have been mined by a single entity that appeared to be active from the network’s earliest phase. Lerner did not claim absolute certainty, but he concluded that “almost all” of the relevant mining pattern likely belonged to one miner, and he visually estimated Satoshi’s fortune at around 1 million bitcoins.
That number quickly became the default shorthand in media coverage and market commentary. It was repeated so often that it came to function less like an estimate and more like an accepted fact. Yet from the beginning, the figure was based on interpretation of mining behavior rather than direct, on-chain proof tied to an identity-confirmed owner.
BitMEX Research revisited that framework and argued that the evidence for attributing such a large share of early mined coins to one person is not as robust as many assumed. The firm did not reject the existence of a dominant early miner outright. Instead, it questioned the confidence level attached to the most widely quoted total and proposed a lower range that still leaves Satoshi with one of the largest bitcoin holdings in existence.
A 30% Reduction Still Leaves an Enormous Stack
If the revised estimate is closer to reality, the difference is substantial. A move from 1,000,000 BTC to roughly 600,000–700,000 BTC implies a reduction of around 30%. In the article’s framing, that would wipe roughly 300,000 BTC from Satoshi’s presumed holdings, equivalent at the time to around $2 billion in notional value.
Even so, the revision does little to change the broader conclusion that Satoshi likely mined and retained a massive amount of bitcoin. Whether the number is 1 million or 700,000, the core market implication remains the same: a giant pool of early coins has remained untouched for years, and participants continue to assume those coins are unlikely to move under normal circumstances.
That said, the exact number matters because it shapes how analysts think about ownership concentration in Bitcoin’s early years. It also affects interpretations of how much of the supply is effectively unavailable to the market. In crypto, narratives around scarcity are often sensitive to small shifts in assumptions, and a difference of several hundred thousand BTC is anything but small.
Why This Matters for Circulating Supply
The question is not just historical curiosity. Bitcoin supply analysis often distinguishes between coins that technically exist on-chain and coins that are realistically available to circulate. Satoshi’s coins are frequently treated in the same category as lost coins: present in the ledger, but removed from practical market liquidity because they are assumed never to be spent.
If Satoshi’s holdings are lower than the widely cited 1 million BTC, then some of the early block rewards attributed to that estimate may instead belong to other early participants. But this does not necessarily mean those coins are likely to enter the market. As noted in the source material, many of those early coins have also remained static since they were first issued as coinbase rewards. In other words, even if Satoshi owns fewer coins than once believed, the effective liquid supply may not increase by much in practical terms.
This nuance matters. Market participants often compress multiple ideas into a single headline number: who mined early, who still controls those coins, whether they are lost, and whether they might someday move. BitMEX Research’s revised estimate does not resolve all of those questions, but it does remind readers that early Bitcoin ownership remains probabilistic, not settled.
The Psychological Weight of Dormant Coins
There is also a psychological dimension to the Satoshi balance question. The market has long treated Satoshi-era coins as a dormant overhang—one that probably never activates, but can never be fully ignored. The mere possibility of those coins moving has always been enough to trigger speculation about panic, sell pressure, or a crisis of confidence.
The article emphasizes that if one assumes Satoshi is a single living entity and is neither dead nor imprisoned, then the continued inactivity of those coins is more plausibly intentional than accidental. BitMEX Research reinforced this idea by citing Satoshi Nakamoto’s own statement: users should never delete a wallet. That quote is used to support the argument that Satoshi likely understood wallet preservation well enough that the coins were not simply lost through negligence.
If that reasoning holds, then the continued dormancy of the coins represents a choice rather than an accident. And if it is a choice, the market must also acknowledge the opposite possibility: a choice can change. That is why any credible sign of movement from coins associated with Bitcoin’s earliest blocks would almost certainly become a major market event.
An Enduring Mystery at the Heart of Bitcoin
What makes this debate so enduring is that it sits at the intersection of Bitcoin’s mythology and its measurable on-chain history. Satoshi Nakamoto remains anonymous. The exact boundaries of early mining activity remain inferential. And one of the largest presumed fortunes in digital asset history has never been publicly verified by the person who supposedly controls it.
BitMEX Research did not close the case; it reopened it. Its contribution was to challenge the certainty surrounding a number that had hardened into convention. A range of 600,000 to 700,000 BTC is still enormous, but it is meaningfully different from the long-cited 1 million BTC figure. For analysts, investors, and historians of Bitcoin, that gap matters.
Until any of the relevant coins move—or stronger evidence emerges—the true size of Satoshi Nakamoto’s bitcoin stash will remain unresolved. Whether the total is 1 million, 700,000, or somewhere in between, the mystery continues to shape how the market thinks about Bitcoin’s early distribution, effective scarcity, and existential tail risks. In that sense, the question is not merely how much Satoshi owns, but what the uncertainty itself means for the story Bitcoin tells about its own beginnings.
