How Much Did Satoshi Nakamoto Spend to Mine 1 Million Bitcoin?
Charles Hoskinson, the founder of Cardano, recently took a stab at estimating just how little electricity Satoshi Nakamoto likely spent to mine those early bitcoins. The numbers are almost laughably low by today’s standards—somewhere under $3,700 total for the first million BTC.
Back in 2009 and 2010, mining was a completely different game. Difficulty was negligible, competition barely existed, and you could mine with a regular computer. No warehouses full of specialized rigs, no six-figure electricity bills. Just a CPU chugging away.
The Three Scenarios
Hoskinson laid out three possible setups Nakamoto might have used. The simplest? A single decent PC or server running at 190 watts, active about 75% of the time over 485 days. In that case, the electricity cost would’ve been around $191. That’s it.
But things get a little more complicated when you factor in the “Patoshi pattern,” a theory developed by researcher Sergio Lerner. By analyzing early Bitcoin blocks, Lerner found evidence suggesting Nakamoto wasn’t mining solo—instead, they likely used a small cluster of machines. If that’s true, costs would’ve been higher: roughly $575 in the U.S., or closer to $1,000 overseas where electricity prices were steeper.
And if Nakamoto had to ramp things up to stay ahead of rising mining difficulty? That’s where the $3,700 figure comes in. Still, even that feels shockingly low compared to today’s mining operations.
The Mystery (and Wealth) of Satoshi
Whoever Nakamoto is—or was—they’re sitting on a fortune now. With Bitcoin’s price surges over the years, their estimated net worth has ballooned to nearly $120 billion, recently putting them ahead of Bill Gates. Not bad for what might’ve been a few hundred bucks in electricity.
Meanwhile, in a separate but vaguely related tidbit, Ripple’s CTO David Schwartz casually mentioned he holds about 250 BTC, bought back when the price was around $30. A modest stash by crypto standards, but you’d have to imagine he’s not complaining.
The whole thing makes you wonder: if mining were still this cheap and easy, would Bitcoin look the same today? Probably not. But it’s a weirdly comforting thought—that the most valuable cryptocurrency in the world started with little more than a spare computer and a few dollars’ worth of power.
