The purpose of the Bitcoin halving:

1. Control Supply, Increase Scarcity .—The block reward for miners is cut in half roughly every four years, limiting the number of new Bitcoins entering circulation.

2. Potentially Drive Price Up — With a limited supply and constant or rising demand, the price of Bitcoin could increase due to scarcity.

3. Combat Inflation –By slowing down new coin creation, halvings aim to minimize inflation within the Bitcoin system.

4. Hard Limit on Total Coins — There's a finite number of Bitcoins (21 million) that will ever be mined. Halvings help us reach that limit.

5. Milestone for Bitcoin —Each halving is a significant event in Bitcoin's history, making it progressively harder to mine new coins and boosting the value of existing ones.
