Bitcoin supply
About 20,109,690 bitcoin had been issued by November 8, 2026, which is 95.76% of the 21 million that will ever exist. The count follows from the block height and the subsidy schedule, which halves every 210,000 blocks. Enter a holding to see it as a share of the cap, or a date to see the supply then.

| Left to mine | 890,310 BTC |

How it works
Supply = the sum of the block subsidy over every block up to the current height. The subsidy started at 50 BTC and halves every 210,000 blocks. New coins a day = the subsidy × 144 blocks, which assumes a block every 10 minutes. Issuance a year = that × 365 ÷ the supply. A future date's supply projects the block count at 144 blocks a day, so it moves if blocks arrive faster or slower.
Frequently asked questions
How many bitcoins are there?
The figure at the top of this page is the number issued by the block height in our latest snapshot. The total can never exceed 21 million, and some coins issued are lost for good.
How many bitcoin are left to mine?
The coins left to mine are 21 million minus the supply issued so far, and the table gives that figure. The last of them will be issued far in the future, since each halving cuts the subsidy.
What is bitcoin's circulating supply?
The issued supply is the usual circulating figure. It counts every coin created, including lost ones, because the network cannot tell which coins are lost.
