First of all, let me talk about how this halving of Bitcoin is different from previous ones!

Bitcoins are generated through a process called "mining," where computers solve computationally intensive problems to earn block rewards of new bitcoins. The issuance of bitcoins is limited by design — approximately every four years, the mining reward is "halved," effectively halving the number of new coins issued.
This deflationary property is a fundamental attraction for many Bitcoin holders. While fiat currency supply is dependent on central banks and precious metal supply is subject to natural forces, Bitcoin’s issuance rate and total supply have been dictated by its underlying protocol since its inception. The combination of a fixed total supply and a gradually decreasing inflation rate not only creates scarcity, but also builds deflationary properties into Bitcoin.
