Bitcoin's Final 929,465 BTC Will Take More Than a Century to Mine

Key Takeaways

• Bitcoin had issued 20.07 million BTC, or 95.57% of nominal supply.
• Bitcoin’s 2028 halving could cut new issuance from about 450 BTC daily to 225 BTC.
• Bitcoin miners may rely entirely on fees around 2140, after block subsidies reach zero.

That is the part often lost in the “BTC is almost fully mined” headline. Yes, 95.57% of the nominal supply is already out there circulating. But the Bitcoin network was built to push most of its issuance into its early years, then make the remaining coins harder and slower to earn. The last few percentage points are not a short countdown. They are most definitely a generational process.

At the time of writing, at 8 a.m. EDT on Aug. 15, 2026, bitcoin miners currently receive 3.125 BTC for each block added to the blockchain. A block is simply a batch of transactions that has been verified and permanently recorded. Bitcoin targets one block about every ten minutes, putting current issuance near 450 BTC a day, or about 164,250 BTC a year if the network stays close to schedule.

Bitcoin’s Supply Faucet Keeps Tightening

The issuance schedule is hard-coded. No central bank can vote to change it, and no government can print more bitcoin in a crisis. Every 210,000 blocks, or roughly every four years, the reward paid to miners is cut in half. Bitcoiners call that event a halving.
