Bitcoin halving events are a very important and remarkable mechanism in the Bitcoin ecosystem. This event, which occurs every 210,000 blocks, occurs approximately every four years and means that the reward miners receive when they create a new block is halved. This was designed by Satoshi Nakamoto in order to keep the total supply of Bitcoin limited and reduce the inflation rate. The halving event is one of the cornerstones of Bitcoin's economic model and creates significant effects on price dynamics.

The first halving occurred on November 28, 2012. On this date, mining rewards decreased from 50 BTC to 25 BTC per block. After this halving, there was a significant increase in the price of Bitcoin. The second halving occurred on July 9, 2016, and rewards were reduced from 25 BTC to 12.5 BTC. After this incident, the Bitcoin price rose again and aroused great interest in the cryptocurrency market. The third halving took place on May 11, 2020 and mining rewards were 12.5.
