Bitcoin has crossed a historic threshold: 20 million of its 21 million total supply has now been mined. The milestone leaves fewer than 1 million coins remaining to be extracted over the next 114 years, according to available data. The achievement underscores how close Bitcoin is to its absolute supply cap.
The extended timeline to extract the final 1 million BTC poses a critical challenge for miners. After the last halving around 2140, miners will depend entirely on transaction fees rather than block rewards to sustain operations—a fundamental shift that may force many current participants out of the industry before the network reaches completion.
