The Bitcoin mining process rewards miners with an amount of bitcoin when they successfully verify a block. And the process is adapting over time. When bitcoin was first launched, the reward was 50 bitcoins. and In 2012, it came down to 25 bitcoins. In 2016, it halved again to 12.5 bitcoins. As of February 2021, miners got 6.25 bitcoins for every new block mined—equal to about $294,168.75 based on February 24, 2021, value. This effectively lowers Bitcoin's inflation rate in half every four years.
The reward will continue to halve every four years until the final bitcoin has been mined. The fact is, the final bitcoin is unlikely to be mined until around the year 2140. However, it's possible that the Bitcoin network protocol will be changed between now and then.
