Bitcoin mining took a direct hit from January’s U.S. winter storm, with Cryptoquant data showing sharp declines in hashrate, production, and miner revenue across the network.
Bitcoin Mining Production Falls to Post-Halving Lows
According to Cryptoquant researchers, several large U.S.-based mining firms curtailed operations as severe weather disrupted power availability, accelerating a networkwide hashrate drawdown of roughly 12%.
Cryptoquant notes this marks the steepest decline since October 2021, pushing total hashrate down massively, its lowest level since September 2025. The researchers emphasize that the weather shock compounded an already fragile setup.
Even before the storm, the firm’s report observes hashrate trending lower as bitcoin corrected from its $126,000 all-time high toward the $100,000 range, tightening margins for miners operating under elevated difficulty conditions.
Mining revenues followed suit. Cryptoquant data shows daily bitcoin mining revenue fell from roughly $45 million on Jan. 22 to a yearly low near $28 million just two days later. While revenue partially recovered to around $34 million by Jan. 26, the analysts stress that earnings remain well below pre-storm levels.
Production metrics paint a similar picture. The report notes that output from the largest publicly traded mining companies dropped from 77 $BTC per day to just 28 $BTC during the disruption. At the same time, production from other miners slid from 403 $BTC to 209 $BTC, underscoring the broad-based nature of the slowdown.
On a 30-day basis, Cryptoquant describes the contraction as the sharpest since mid-2024, shortly after the last bitcoin halving. Publicly traded miners saw production fall by as much as 48 $BTC, while other miners collectively lost about 215 $BTC over the same period, according to the firm’s on-chain tracking.
Profitability indicators are flashing deeper stress. Cryptoquant’s Miner Profit/Loss Sustainability Index fell to 21, the lowest reading since November 2024. The firm interprets this level as signaling that miners are “extremely underpaid” under current price and difficulty conditions.
Notably, analysts point out that this strain persists even after multiple downward difficulty adjustments over the past five epochs. Lower difficulty has offered some relief, but not enough to offset weaker prices, reduced block production, and weather-related outages.

From Cryptoquant’s perspective, the episode highlights how external shocks, such as extreme weather, can ripple quickly through bitcoin’s mining economy. Concentration of large-scale mining operations in the U.S. has increased the network’s exposure to regional disruptions, a theme the firm has flagged in prior research.
Looking ahead, the researchers suggest that sustained recovery in miner profitability will likely depend on a combination of improved price conditions, stable energy availability, and time for difficulty to recalibrate. Until then, the firm’s data indicates miners remain under pressure, even as the storm itself clears.
