The Bitcoin hashrate has reached its lowest point in seven months due to the brutal winterstorm of USA. Network computing power tumbled over 40% in just two days, dipping to around 663 exahashes per second (EH/s) by Sunday before clawing back to 854 EH/s on Monday. This dramatic drop highlights the vulnerabilities in mining concentration but also miners' growing role as grid saviours during crises.​

Storm Chaos Triggers Miner Shutdowns

A colossal storm system was ripping through over three dozen states, dumping heavy snow, ice, and sub-zero temperatures that knocked out power for nearly a million customers. Electricity grids groaned under the strain, especially in mining hotspots like Texas's ERCOT and PJM regions. Miners, responsible for about 38% of global hashrate from the US, voluntarily curtailed operations to avoid blackouts. Foundry USA, the top mining pool with a usual 30%+ network share, saw its hashrate crater 60%, shedding nearly 200 EH/s since Friday, down to 198 EH/s. Block times stretched to 12 minutes at the peak, and Luxor also offline'd over 110 EH/s. Oregon's Abundant Mines called it "40% of global capacity offline," underscoring the scale.

BTC Holds Steady Despite the Dip

Markets barely blinked. Bitcoin traded around $87.5k on Monday, down just 0.77% intraday after slipping below $88,000. The seven-day smoothed hashrate hovered near 951 EH/s before the plunge, now recovering as weather eases. Difficulty faces a 5% recalibration soon, potentially boosting profitability for survivors, per JPMorgan's take: when hashrate falls, the online miners feast on easier rewards. Bitcoin's total market cap sits firm above $1.7 trillion, with dominance at 56%. Ethereum lags at $330 billion, while top alts like XRP and Solana hold some gains. US spot BTC ETFs, post-$50B inflows last year, saw minor outflows but nothing storm-shaking. Stablecoins like USDT churned $4T+ annually, keeping liquidity flowing.​

Grid Warriors or Weak Link?

Research from Daniel Batten flips the script: flexible mining absorbs renewables' excess and ramps down during peaks, cutting consumer costs and bolstering grids. With AI datacenters now vying for megawatts, Bitcoin's "interruptible load" edge shines. Hashlabs projects hashrate hitting 1.7 ZH/s by end-2026, but storms expose geographic risks in US-heavy ops. CryptoQuant's Julio Moreno flagged slashed output at Marathon, Riot, and CleanSpark. Still, no security scares, the network stayed robust. As storms fade, expect a full rebound, but this saga spotlights diversification needs.
