- Bitcoin’s circulating supply is about 20.05 million $BTC, or 95.47% of the 21 million cap, leaving roughly 950,000 $BTC to be issued.
- The next halving is expected in 2028, reducing the block reward from 3.125 $BTC to 1.5625 $BTC as issuance continues slowing toward 2140.
- After the final Bitcoin is mined, miners would continue securing the network but rely entirely on transaction fees, making future block-space demand central to sustainability.
Bitcoin’s approaching 2140 milestone sounds like the end of mining, yet it actually marks the end of new coin issuance. Circulating supply currently stands near 20.05 million $BTC, representing 95.47% of Bitcoin’s fixed 21 million maximum, with roughly 950,000 $BTC still waiting to enter circulation. The strange reality is that almost all Bitcoin already exists, but the final fraction may require more than a century to emerge. That extraordinary delay comes from a monetary schedule designed to slow issuance repeatedly rather than stop it through one sudden, dramatic event for miners worldwide over future decades.
