Mining margins collapse amid falling Bitcoin prices

A major US winter storm cut mining output and pushed daily revenues to yearly lows, adding to pressure from weaker crypto markets.

Bitcoin mining profitability has hit a 14-month low as falling prices, high difficulty, and extreme weather combine to squeeze operators’ margins.

CryptoQuant data shows Bitcoin mining profitability has fallen to its weakest level in 14 months, as declining prices and rising operational pressure weigh on the sector. The miner profit and loss sustainability index dropped to 21, its lowest reading since November 2024.

Lower Bitcoin prices and elevated mining difficulty have left operators ‘extremely underpaid’, according to the report. Network hash rate has also declined across five consecutive epochs, reaching its lowest level since September 2025 and signalling reduced computing power securing the network.

Severe winter weather across parts of the eastern United States added further strain, disrupting mining activity and pushing daily revenues down to around $28 million, a yearly low. Weaker risk appetite across equities and digital assets has compounded the impact.

Shares in listed miners such as MARA Holdings, CleanSpark, and Riot Holdings have fallen by double-digit percentages over the past week. Data from the Cambridge Bitcoin Electricity Consumption Index shows mining BTC now costs more than buying it on the open market, increasing pressure on weaker operators.
