A powerful winter storm sweeping the United States delivered a sharp reminder that Bitcoin mining ultimately answers to weather, not markets. Over the weekend, hashrate plunged about 40% in two days to roughly 663 exahashes per second (EH/s), the lowest level in seven months, as miners throttled or powered down rigs to relieve stress on strained power grids.
Hashrate Drops to 663 EH/s, Rebounds to 854 EH/s
AccuWeather reported the storm hammered over three dozen US states with heavy snow, ice and sub-zero temperatures, leaving roughly one million customers without electricity. Data from CoinWarz showed hashrate began sliding Friday and "plunged sharply" over the weekend to 663 EH/s by Sunday, a drawdown of more than 40% in 48 hours. The network has since rebounded to about 854 EH/s as of Monday. Oregon-based miner Abundant Mines called the shock "significant," estimating "approximately 40% of global Bitcoin mining capacity has gone offline in the past 24 hours due to extreme winter weather," with many operators voluntarily reducing output as demand spiked.
Miners as "Flexible Load" for Power Grids
The company framed this flexibility as a structural edge, noting mining farms can shut down rapidly during grid stress and restart just as fast when conditions normalize. This dynamic is especially visible in the US, which Hashrate Index estimates now contributes nearly 38% of global hashrate and hosts at least 137 crypto-mining facilities per a 2024 Energy Information Administration report. Industry advocates argue this episode bolsters the case that miners act as "flexible load" rather than pure parasites. Bitcoin ESG researcher Daniel Batten noted on X that demand response programs involving miners helped stabilize the Texas grid during the storm, as operators curtailed usage to free up capacity for households and critical infrastructure.
Prices Stay Calm Amid Hashrate Shock
Despite the mining disruption, crypto prices traded in a far calmer fashion. Bitcoin is changing hands near $87,913 today, up modestly from $86,567 24 hours earlier. Ether trades around $2,930, edging 0.3% higher day-on-day. Solana sits near $124.57 after a roughly 1.4% gain over the past 24 hours. For miners, the weekend was less about price action and more about proving—once again—that their business is tightly coupled to real-world weather and grid conditions, not just digital charts.
