The halving events of cryptocurrencies such as Bitcoin and Litecoin reduce the rewards for miners. After the fourth halving of Bitcoin in 2024, the block reward was reduced to 3.125 BTC. The average mining cost per Bitcoin for miners is pegged at $37,856. Without a sustained rise in the price of Bitcoin, it will be difficult for miners to make a profit. Litecoin also experienced a halving of block rewards in 2024, and the supply reduction may provide support for price rebounds in 2025, but it still faces pressure from rising energy costs.
