First work of a three part series on the 2020 Bitcoin Halving on Block 630 000 ----- Bitcoin was designed as a deflationary currency. Bitcoin halving happens every 210,000 blocks and reduces the reward for 50 percent every time in a geometrical progression. As of now, the block reward is 12.5 coins per block and will decrease to 6.25 coins per block post halving. The block will keep on halving until the block reward per block becomes 0. That will happen approximately by year 2140. As Bitcoin will become more scarse in the future it will fragment into millions of pieces as it does in BTC Halving 1/3.
