Bitcoin supply approaching 20 million: The final million will take another 114 years to mine
TL;DR
Bitcoin is approaching 20 million coins in circulation, with over 95% of its total 21 million supply already mined. The final million coins will take about 114 years to mine, with 99% expected by 2035 and the last coin around 2140.
Key Takeaways
- •Bitcoin's circulating supply is nearing 20 million, representing over 95% of its total fixed supply of 21 million coins.
- •The remaining 1 million coins will take approximately 114 years to mine, with 99% expected by January 2035.
- •Bitcoin's issuance rate slows through halving events, currently producing about 450 BTC daily with inflation below 1%.
- •The fixed supply cap creates absolute scarcity, contrasting with fiat currencies and establishing Bitcoin as 'hard money'.
- •Miners will eventually rely entirely on transaction fees as block rewards diminish, shifting the network's economic model.

Bitcoin BTC$67,418.96 is on the brink of reaching a major symbolic milestone with the issuance of its 20 millionth coin.
According to the Clark Moody Dashboard, 19,996,979 BTC have been mined, leaving just roughly 3,000 BTC remaining before the 20 millionth bitcoin is reached, roughly seven days away at current issuance rates. Once that threshold is crossed, more than 95% of the fixed 21 million supply will be in circulation, with just 1 million coins left to be mined over the next century.
Satoshi Nakamoto hard coded the 21 million cap into bitcoin’s protocol to create a form of money with absolute scarcity, contrasting sharply with fiat currencies that can be expanded by central banks. Although Satoshi never fully explained the specific number, the fixed limit established credibility around predictable supply. For bitcoin maximalists, the cap is foundational. Any suggestion of changing it is seen as undermining Bitcoin’s core value proposition as “hard money.”
Bitcoin’s scarcity is often compared to gold or oil. But while commodity supply can respond to higher prices through increased production or new discoveries, bitcoin’s issuance cannot accelerate. Its supply curve is transparent and immutable.
Issuance has slowed through halvings, which cut miner rewards roughly every four years, pushing inflation below 1%, with about 450 BTC mined daily. At this pace, 99% of supply will be mined by January 2035. The final full bitcoin is expected around 2105, with fractional issuance continuing until about 2140.
After that, miners will rely entirely on transaction fees. For supporters, the 20 million milestone reinforces bitcoin’s scarcity narrative as new supply dwindles. While for miners it underscores the long term shift toward a fee driven revenue model that will ultimately determine the network’s security and economics.
- Sygnum Bank CIO Fabian Dori says bitcoin’s pullback is a liquidity-driven squeeze, not a structural breakdown in fundamentals.
- Sentiment is at extreme fear levels, leaving markets vulnerable to further volatility and downside.
- Improving business cycle data, stablecoin growth and institutional adoption support a constructive long-term outlook, according to Dori.
