The Bitcoin hashrate drop is hitting hard as extreme winter storms cripple US electricity grids, forcing major mining pools to throttle operations. An Arctic cold snap has blanketed the country in subfreezing temperatures, spiking heating demands and straining power supplies from Texas to New England. Foundry USA and Luxor, two dominant North American pools, have slashed their contributions by over 110 EH/s combined, sending network-wide hashrate tumbling.
This isn’t just a blip; it’s a stark reminder of mining’s vulnerability to real-world chaos. With grids issuing conservation alerts and power outages leaving millions in the dark, miners are curtailing rigs to avoid blackouts. Meanwhile, underlying pressures like low BTC prices and soaring energy costs compound the pain, as seen in recent Bitcoin hash rate falls amid miner capitulation.
Expect ripples through the network: slower block times, potential security dips, and a test of miners’ resilience. As we unpack this Bitcoin hashrate drop, we’ll dive into the data, grid dynamics, and what it means for the industry’s future.
Arctic Freeze Triggers Massive Bitcoin Hashrate Drop
The brutal Arctic weather has turned mining hubs into frozen battlegrounds, prompting immediate operational cutbacks. Subzero temps and ice storms have overwhelmed power infrastructure, leading to emergency conservation requests across multiple states. Major pools like Foundry USA saw hashrate plummet from 340 EH/s to 242 EH/s in days, a drop that’s since worsened.
Luxor followed suit, sliding from 45 EH/s to 26 EH/s, while Antpool and Binance Pool notched smaller but notable retreats. Hashrate Index data pegs Foundry at 163.5 EH/s now, good for 22.59% of the network, with Luxor at 3.01% and 21.9 EH/s. This collective pullback has slowed block production to around 12 minutes, per reports from TheMinerMag.
These aren’t isolated incidents; they’re symptoms of mining’s heavy reliance on strained US grids. As Texas Bitcoin mining faces ongoing nightmares, the broader network feels the chill.
Pool-by-Pool Breakdown of the Hashrate Cuts
Foundry USA, the globe’s biggest pool, bore the brunt with a staggering 60% hashrate reduction since Friday, equating to nearly 200 EH/s offline. This isn’t voluntary efficiency play; it’s survival amid grid alerts that prioritize residential heating over crypto rigs. Temporary halts have disrupted steady block minting, introducing volatility in transaction confirmations.
Luxor’s decline mirrors this, shedding nearly half its power as operators in affected regions unplug to comply with demand response programs. Smaller pools like Antpool trimmed edges, but the big players dominate the damage. CryptoQuant notes this coincides with miner reserves hitting 2010 lows, signaling capitulation under price pressure.
Analysts point to on-chain flows: miners offloading BTC to cover costs, exacerbating the Bitcoin hashrate drop. It’s a vicious cycle where weather woes meet financial squeezes.
Network-Wide Impacts from the Sudden Decline
Total network hashrate dipped sharply, with some reports claiming a 30% plunge or 260 EH/s lost in hours, shutting down 1.3 million rigs. Block times stretched, raising centralization risks as fewer pools shoulder more load. Security holds for now, but prolonged drops could invite 51% attacks, though probability remains low.
Hashrate Index charts illustrate the chaos: Foundry’s dominance wanes temporarily, redistributing power to Asian pools less exposed to US weather. Yet recovery hinges on grids stabilizing. This event underscores mining’s geographic risks, pushing calls for diversification.
In context of miner capitulation trends, this drop accelerates reserve drawdowns, pressuring prices further.
Grid Strain and Miner Demand Response in Action
Power grids under siege from the storm issued urgent pleas for conservation, hitting miners square in the energy-intensive core. States from Texas to the Northeast saw spikes in demand, with outages affecting over a million homes and claiming lives. Operators like those tied to CLSK, RIOT, and BTDR are wired into programs like TVA’s demand response, allowing quick curtailments.
Matthew Sigel of VanEck highlighted this flexibility on X, noting miners’ role in easing strain during crises. They’ve proven value before, ramping down to free power for essentials. Yet confirmation of real-time cuts for this storm lags, leaving questions on scale.
This dynamic reveals miners as unwitting grid stabilizers, but at what cost? As energy prices hit 18.07 cents/kWh last year, margins evaporate. Links to Trump’s emergency power auction offer hope, but it’s long-term.
How Demand Response Programs Save Grids
Demand response lets utilities signal miners to idle rigs, earning credits or priority access later. TVA and similar setups have miners curtail gigawatts swiftly, proven in past Texas freezes. This storm tests the model anew, with public miners in hot zones primed to respond.
Benefits are mutual: grids avert blackouts, miners dodge penalties. Sigel’s post flags capacity in affected areas, though execution varies by operator. Data lags, but history shows it works when grids tighten.
Critically, it exposes overreliance on fossil-heavy grids, spurring shifts to stranded energy or hydro.
Human and Economic Toll of the Winter Storm
BBC reports three dead, schools shuttered, flights grounded amid life-threatening cold. Hundreds of thousands lost power, amplifying chaos for mining ops stacked in vulnerable spots. Economic hits include delayed blocks and miner revenues already at historic lows.
Miners face dual whammy: storm-forced downtime atop subdued BTC prices around $92k. CryptoQuant’s miner reserve data screams pressure, lowest since 2010. Many teeter unprofitable, prompting pivots like Bitfarms to AI.
Underlying Pressures Amplifying the Bitcoin Hashrate Drop
Beyond weather, miners grapple with squeezed margins from high energy costs and flat prices. September 2025 saw electricity at record highs, up 10.5% yearly. Revenues cratered, pushing sales and hashrate reductions even pre-storm.
Bitfarms reallocates to HPC, signaling diversification. Broader sector eyes US bank charters and stablecoins, per recent analyses. Yet immediate survival demands cheap power and response agility.
This Bitcoin hashrate drop layers onto trends like Bitcoin downside risks from macro data.
Miner Capitulation and Reserve Drawdowns
CryptoQuant charts show reserves at 2010 lows, miners dumping to fund ops. Subdued prices near $92k fail to offset costs, hastening capitulation. Hashrate bottoms often precede rebounds, but pain lingers.
On-chain inflows spike from mid-large holders, hinting distribution. Combined with weather, it’s a perfect storm for hashrate.
Shifts in Business Models Amid Crisis
Firms like Bitfarms pivot to AI, leveraging rigs for compute. Others chase Trump’s $15B power auction for capacity. Long-term, tokenization and RWA could reshape, but short-term grit rules.

What’s Next for Bitcoin Mining Post-Storm
Hashrate should rebound as weather eases, but scars remain: elevated costs, regulatory scrutiny, quantum threats looming. Trump’s power plans promise relief, yet grids need upgrades. Miners must diversify geographically and technologically.
Optimists eye ETF inflows and cycles peaking in 2026, per Bitcoin cycle peaks. Pessimists warn of prolonged capitulation. Network resilience holds, but this drop tests it.
Stakeholders watch for sustained recovery, grid reforms, and policy wins to stabilize the sector amid volatility.
