What is the bitcoin halving? When is the bitcoin halving happening?
The bitcoin protocol specifies that the reward for adding a block will be halved every 210,000 blocks (approximately every four years). New bitcoins are created roughly every ten minutes and the rate at which they are generated drops by half about every four years until all will be in circulation. Block reward reduction will begin somewhere in May 2020.
Block time: 10 minutes
New reward =₿12.5 > ₿ 6.25
