Bitcoin supply nears 20 million as final million coins will take 114 years to mine

Bitcoin is approaching a major symbolic milestone, with nearly 20 million coins now mined out of its fixed 21 million supply.

Out of the total cap, more than 95% of all bitcoin that will ever exist is already in circulation. The cryptocurrency was trading around $71,225 as the network moved closer to issuing its 20 millionth coin.

Data from the Clark Moody Dashboard shows that 19,996,979 BTC have been mined so far, leaving roughly 3,000 coins before the 20 million mark is reached. At the current issuance pace, the milestone could arrive in about a week. Once crossed, only about 1 million bitcoin will remain to be mined over the next century.

Bitcoin’s creator, Satoshi Nakamoto, embedded the 21 million coin limit directly into the protocol to establish a form of money defined by absolute scarcity. The hard cap stands in contrast to fiat currencies, whose supply can expand through central bank policy. While Nakamoto never provided a detailed explanation for choosing the specific number, the fixed limit created a predictable supply schedule that has become central to bitcoin’s value proposition.

For many bitcoin proponents, the supply cap is a foundational principle. Any discussion about altering it is widely viewed as contradicting the asset’s role as a form of “hard money.”

Bitcoin’s scarcity is frequently compared to commodities such as gold or oil. However, unlike physical resources—where production can increase when prices rise—bitcoin’s issuance cannot be accelerated. Its supply curve is predetermined and transparent.

New supply continues to slow through the network’s halving cycles, which reduce miner rewards roughly every four years. Following these reductions, bitcoin’s inflation rate has fallen below 1%, with around 450 BTC currently mined each day.

At this pace, roughly 99% of the total supply will be mined by January 2035. The final whole bitcoin is expected to be produced around 2105, with increasingly small fractional amounts continuing to be issued until approximately 2140.

After that point, miners will depend entirely on transaction fees for revenue. For supporters, the approaching 20 million milestone reinforces bitcoin’s narrative of digital scarcity, while for miners it highlights the long-term transition toward a fee-driven economic model that will ultimately shape the network’s security.
