Bitcoin halvings are a key part of the Bitcoin protocol. They occur every 210,000 blocks, which is approximately every four years. During a halving, the reward for mining a block is reduced by half. This means that the supply of new bitcoins entering the market is reduced by half.
There will be a total of 32 Bitcoin halvings. The last halving is expected to occur in the year 2140. After the last halving, there will be no new bitcoins created, and the total supply of bitcoins will be 21 million.
Bitcoin halvings are important because they help to control the inflation rate of Bitcoin. By reducing the supply of new bitcoins entering the market, halvings help to keep the value of Bitcoin stable.
So far, there have been three Bitcoin halvings. The first halving occurred in 2012, the second halving occurred in 2016, and the third halving occurred in 2020. The next halving is expected to occur in 2024.
Bitcoin halvings are a significant event in the Bitcoin community. They are often followed by a bull market, as investors anticipate the reduced supply of new bitcoins entering the market.
