Where the 21 million limit comes from
Bitcoin's software pays miners a fixed reward for each block, which started at 50 BTC in 2009 and halves every 210,000 blocks. Added up, the rewards approach 21 million but never reach it: rounded down to whole satoshis, the total is just under 20,999,999.98 BTC.
Not every mined coin can be spent: studies estimate several million bitcoins are lost for good (forgotten keys, early coins never moved). So the coins actually available are fewer than the supply shown here.
