Recently, the difficulty of mining Bitcoin has decreased by about 11%, the sharpest drop since China's ban on Bitcoin mining in 2021. The main reasons are the drop in Bitcoin price, which makes mining costs higher than the selling price, and winter storms in the United States that forced many mining operations to shut down. When fewer people are mining, the Bitcoin network automatically reduces its difficulty to balance things out. This makes it easier for the remaining Miners to earn rewards, but profitability still depends on whether the price of Bitcoin rises again.
