New data paints a clearer picture of how the January winter storm in the U.S. affected bitcoin mining activities, showing that daily production among publicly traded miners dropped sharply during the disruption.
The storm ripped through huge swathes of the continental United States, forcing miners to curtail operations due to grid strain, snow, ice and extreme cool, and highlighted how closely mining activities are now tied to energy market conditions.
According to data shared by CryptoQuant’s head of research Julio Moreno, daily production among listed miners tracked by CryptoQuant typically ranged from 70 to 90 Bitcoin (BTC) in the weeks leading up to the storm, before dropping to around 30 to 40 BTC per day at the height of the disruption.
Production later showed partial signs of recovery from low levels as weather conditions improved, suggesting the decline reflected ephemeral and largely voluntary restrictions.
A previous Cointelegraph report analyzed how the storm coincided with a decline in Bitcoin hashrate in the US and a rally in mining stocks. The latest production data provides further detail on the extent of operational disruption.
Miners tracked by CryptoQuant include Core Scientific (CORZ), Bitfarms (BITF), CleanSpark (CLSK), MARA Holdings (MARA), Iris Energy (IREN), and Canaan (CAN), which also has self-mining operations.
Among them, miners with major US operations include Core Scientific, CleanSpark, Marathon, Riot Platforms, TeraWulf and Cipher Mining.

A more challenging environment for miners
The winter storm disruption comes as Bitcoin miners are already navigating a challenging operating environment, illustrating how external shocks can enhance existing pressures on the sector.
While miners have long been recognized for their ability to assist stabilize power grids by balancing load and responding to demand, broader economic and market conditions have weighed heavily on profitability. Falling Bitcoin prices and network hashrates, combined with steadily rising operating costs throughout 2025, have tightened margins across the industry.
Last year, industry publication The Miner Mag described the situation as the “toughest margin conditions of all time,” citing increased energy costs, capital constraints and post-halving revenue compression.
Cointelegraph previously reported that these pressures are expected to intensify through 2026 as miners grapple with lower margins, consolidation and a growing shift towards artificial intelligence and high-performance computing as alternative sources of revenue.
