Bitcoin Just Crossed 20 Million Coins Mined: Only 1 Million Remain

Seventeen years after the genesis block, Bitcoin has issued 95.24% of its total supply, leaving fewer than one million coins left to mine across the next 114 years.

What the Chart Shows

The Bitcoin Magazine Pro miner revenue chart tells the story more clearly than any supply table. The orange line tracking block rewards peaked above 15,000 BTC per block in Bitcoin’s earliest years, then stepped down at each halving date in a staircase pattern that has been moving in one direction since 2012. Today that line sits near the bottom of the chart. Not because mining stopped. Because the protocol is working exactly as designed.

Each halving cuts the reward in half. The 2024 halving brought it to 3.125 BTC per block. The 2028 halving will cut it again. By the time the final coin is mined sometime around 2140, block rewards will have become mathematically negligible long before the last satoshi is issued.

The Number That Reframes the Scarcity Argument

One million coins remain. That sounds like a lot until the timeline lands. The first 20 million took 6,267 days to mine. The final million will take approximately 41,610 more. The halving schedule does not just reduce supply issuance. It stretches the remaining supply across a timeframe longer than most institutions currently operating will exist.

Miners earning those final coins will depend almost entirely on transaction fee revenue. Block rewards will have long since become irrelevant to their economics. Whether fee markets scale sufficiently to sustain network security at that point is the open question embedded in every block mined today.

The supply is nearly complete. The experiment is far from over.
