For adding blocks to the blockchain, miners receive a reward in the form of a few bitcoins; the reward is halved every 210,000 blocks. The block reward was 50 new bitcoins in 2009 and is currently 12.5. On May 11th, 2020 the third halving occurred, bringing the reward for each block discovery down to 6.25 bitcoins.5 A variety of hardware can be used to mine bitcoin but some yield higher rewards than others.
