Mining a Bitcoin block needs to be costly to ensure that the gains from an attack on the blockchain are less than the cost of mounting it. Miners have two sources of income to defray their costs, the block rewards and the fees for the transactions in the block.
On April 19th the block reward was halved from 6.25BTC to 3.125BTC. This process is repeated every 210,000 blocks (about every 4 years). It limits the issuance of BTC to 21M because around 2140 the reward will be zero; a halving will make it less than a satoshi.
Long before 2140 the block rewards will have shrunk to become insignificant compared to the fees. Below the fold I look at the significance of the change to a fee-only Bitcoin
