New data provides a clearer picture of how January's US winter storm affected Bitcoin mining operations, showing that day by day production from listed miners fell sharply in the course of the disruption.
The storm swept across much of the continental United States, causing miners to curtail operations resulting from grid stress, snow, ice and extreme cold, and underscoring how closely mining activity has turn into tied to energy market conditions.
Daily production from publicly traded miners tracked by CryptoQuant typically averaged between 70 and 90 Bitcoin (BTC) within the weeks leading as much as the storm, before falling to around 30 to 40 BTC per day at the height of the disruption, based on data from Julio Moreno, head of research at CryptoQuant.

Output later showed partial signs of recovering from its lows as weather conditions improved, suggesting the decline reflected temporary and largely voluntary cuts.
Previous reports from Cointelegraph examined how the storm coincided with a drop within the U.S. Bitcoin hash rate and a rally in mining stocks. The latest production data provides further details on the extent of the disruption.
Miners tracked by CryptoQuant include Core Scientific (CORZ), Bitfarms (BITF), CleanSpark (CLSK), MARA Holdings (MARA), Iris Energy (IREN), and Canaan (CAN), which also operates a self-mining company.
Miners with large US operations include Core Scientific, CleanSpark, Marathon, Riot Platforms, TeraWulf and Cipher Mining.
A tougher environment for miners
The disruption from the winter storm comes at a time when Bitcoin miners are already coping with a difficult operating environment, showing how external shocks can add to existing pressures on the sector.
While miners have long been known for his or her ability to assist stabilize power grids through load balancing and demand response, overall economic and market conditions have severely impacted profitability. Falling Bitcoin prices and network hashrate coupled with ever-increasing operating costs throughout 2025 have squeezed margins across the industry.
Last yr, industry publication The Miner Mag described the situation as “the hardest margin environment ever,” citing increased energy costs, capital constraints and a drop in revenue following the halving.
Cointelegraph previously reported that these pressures are expected to accentuate through 2026 as miners contend with lower margins, consolidation and an increasing shift toward artificial intelligence and high-performance computing as alternative revenue streams.
