Bitcoin is nearing a notable milestone as the total number of coins mined approaches 20 million, bringing the network closer to exhausting most of its fixed supply.
Of the maximum 21 million bitcoin that will ever exist, more than 95% are already in circulation. With bitcoin trading around $71,225, the network is expected to soon produce 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 threshold is reached. At the current issuance rate, that point could arrive within about a week. After crossing the milestone, only around 1 million bitcoin will remain to be mined over the coming century.
Bitcoin’s pseudonymous creator, Satoshi Nakamoto, embedded the 21 million supply cap directly into the protocol to ensure a form of money defined by strict scarcity. The limit stands in contrast to fiat currencies, whose supply can be expanded through central bank policy. While Nakamoto never clearly explained why the specific number was chosen, the cap established a transparent and predictable supply schedule.
For many bitcoin advocates, that hard limit is central to the asset’s value proposition. Any suggestion of altering it is often viewed as undermining bitcoin’s identity as a form of “hard money.”
Bitcoin’s scarcity is frequently compared to commodities like gold or oil. However, unlike physical resources—where higher prices can lead to increased production or new discoveries—bitcoin’s issuance cannot accelerate. Its supply curve is fixed and publicly known.
The pace of new supply has slowed over time through the network’s halving events, which reduce miner rewards roughly every four years. As a result, bitcoin’s inflation rate has dropped below 1%, with about 450 BTC currently mined each day.
At this pace, roughly 99% of bitcoin’s total supply is expected to be mined by January 2035. The final whole bitcoin is projected to be issued around 2105, with smaller fractional amounts continuing to be produced until about 2140.
Once block rewards are fully exhausted, miners will depend entirely on transaction fees for revenue. For supporters, the approach of the 20 million milestone reinforces bitcoin’s scarcity narrative, while for miners it highlights the long-term transition toward a fee-driven economic model that will ultimately support the network’s security.
