Bitcoin Halving is the event that halves the block reward for Bitcoin miners, occurring every 210,000 blocks (approximately every 4 years). This mechanism is designed to control the supply of Bitcoin, ensuring that the total circulating Bitcoin does not exceed 21 million. When Halving occurs, the block reward is reduced from its previous level to half, decreasing the rate at which new Bitcoin is released. This creates scarcity, often leading to an increase in the value of Bitcoin in the long term. The Halving event not only affects the price of Bitcoin but also mining operations, as miners face higher costs and lower profits. Halving is a core factor in maintaining the sustainability and value of Bitcoin.
