The Bitcoin network has passed a major supply milestone, with the 20 millionth BTC mined out of its permanent 21 million cap. Data shows 95.2% of the total supply is now in circulation, underscoring the network’s predictable and transparent issuance schedule. The final million coins will be mined over more than a century, with increasing difficulty due to scheduled halving events that reduce miner rewards.
The Bitcoin network has officially mined its 20 millionth BTC, a monumental step toward its permanent scarcity with a total supply capped at 21 million. This event highlights the network’s transparency and hardcoded predictability, unlike traditional fiat currencies.
Data from BiTBO shows that 95.2% of Bitcoin’s total supply, representing exactly 20,000,018.75 BTC, has been mined. The remaining one million coins will be mined with increasing difficulty due to the network’s halving mechanism.
Halvings take place roughly every four years, slashing the rewards miners receive for adding new blocks by 50%. “The more time passes, the harder it will become to mine BTC,” with estimates predicting the last coin will be mined in 2140.
This structure highlights Bitcoin’s core concept of digital scarcity, a feature often compared to gold. Millions of BTC are also believed to be permanently lost, potentially making the effective circulating supply even lower.
The last Bitcoin halving occurred in 2024, reducing the block reward from 6.25 to 3.125 BTC. The next one is expected in approximately two years, further reducing the new supply entering circulation.
Currently, only about 450 BTC is mined daily, meaning only a tiny fraction of the remaining BTC will be in circulation by 2030. This means miners will rely increasingly on transaction fees as the block reward continues its scheduled decline.
