Bitcoin mining difficulty has decreased by 2.37% as of November 12, 2025, according to data from Cloverpool. The difficulty level now stands at 152.27 trillion, requiring miners to compute approximately 152 trillion hash functions to add a block to the Bitcoin network and earn 3.125 BTC. This adjustment, which occurs bi-weekly, is designed to maintain a consistent issuance rate of new Bitcoin. This marks the second decrease in mining difficulty in four months, following a significant 33% increase in July. Anton Gontarev, commercial director at Intelion, characterized the adjustment as a market 'equalization' rather than a sign of weakness, emphasizing that mining remains profitable with monthly returns ranging from 2.7% to 3.8%.
