Bitcoin circles talk about computing power every day. But few ask a more basic question: how long can those mining rigs roaring 24 hours a day hold up when extreme weather hits? Over the past two days, the answer arrived.

On January 23, 2026, an Arctic blast swept across North America.

The U.S. National Weather Service warned that 22 states had entered states of emergency, 160 million people faced extreme cold, and power outages were spreading across multiple regions.

Bitcoin’s network computing power plunged in response. According to TheMinerMag, the computing power of Foundry USA, the world’s largest mining pool, fell from 340 EH/s to 242 EH/s within 48 hours.

Luxor’s mining pool dropped from 45 EH/s to 26 EH/s. Roughly 260 EH/s of network computing power went offline, equivalent to 1.3 million mining rigs shutting down at once.

Open the computing power distribution map, and North America’s once-dense heat spots suddenly turn into vast blank spaces.

Computing Power Evaporates, Miners Win by Standing Still

On January 22, 2026, Winter Storm Fern swept from Texas to New England, leaving tens of millions of Americans shivering in snow and ice.

At the same time, 110 EH/s of computing power suddenly “evaporated” from the global Bitcoin network, equal to nearly one-fifth of the network’s total computing capacity disappearing in an instant.

Foundry USA, the world’s largest mining pool, saw its computing power plunge 60% in three days, while Bitcoin block times stretched from the normal 10 minutes to 12 minutes.

The mining rigs did not freeze. Miners shut them down voluntarily, for a simple reason: turning them off was more profitable than keeping them on. Texas grid operators classify miners as “large flexible loads” — in plain terms, backup capacity.

Hospitals, fire stations, and residential power get priority. Miners can be unplugged at any time, but when they are, the grid has to compensate them. During the storm, Texas wholesale electricity prices briefly surged to several dollars per kilowatt-hour, compared with just a few cents in normal times.

One Texas mining farm operator said privately: “When power prices get that high, we shut down immediately. Instead of losing money crypto mining, it’s better to sell power back to the grid and earn the spread while doing nothing.”

This playbook is called “demand response.”

Publicly listed miner Riot Platforms made $31.7 million simply by shutting down during a heat wave in August 2023. In the third quarter of 2025, Riot’s demand response revenue reached $30.6 million, up 147% year on year.

Matthew Sigel, head of digital assets research at VanEck, wrote on X that listed miners such as CleanSpark and Riot had already built “being sacrificed in exchange for subsidies” into their business models.

ERCOT also said the grid did not enter an emergency state this time. Miners shut down purely as a business decision after running the numbers: being backup pays better than being the main act.

Gas Prices Surge, Balance Sheets Bleed

If grid instructions are administrative intervention, market prices are where the real fight begins.

On January 19, 2026, Jinshi Data issued a warning: U.S. natural gas futures had jumped 15% intraday.

Winter Storm Fern swept from Texas to New England, exposing more than 200 million Americans to freezing temperatures.

Natural gas prices soared. Official pricing data showed mid-January prices at about $4, significantly above the average for the same period in 2025, and miners’ ledgers began to bleed.

About 40% of U.S. electricity depends on natural gas generation. When gas prices double, power prices take off with them.

“Turning machines on at a time like this is just throwing money into the fire,” one Texas mining farm owner said.

The Illusion Breaks, Reality Hits Back

The most interesting part of this episode is that it acts like a mirror, reflecting Bitcoin’s most awkward predicament.

We talk every day about “decentralization,” and imagine Bitcoin as free and unstoppable.

But reality is less flattering: as computing power becomes increasingly concentrated in North America, Bitcoin’s security is starting to depend on the weather.

When extreme weather strikes, global computing power sneezes along with it.

One analyst who has long tracked the mining industry sighed privately: “Wasn’t this supposed to be a distributed network? How did it become a giant bet on one region’s energy system?” The bosses of Texas mining companies sketch grand Web3 visions in their pitch decks, while checking weather forecasts on their phones every day.

The most cutting-edge digital asset is still, in the end, held hostage by the oldest forces: climate and electricity.

The Arbitrage Maze, and the Hidden Winners

Who were the real winners in this cold snap?

Miners appeared to make money: selling power at high prices, taking subsidies for shutting down, and winning on both ends. It sounds attractive, but it feels off when you think it through.

Miners are supposed to live off computing power. Whoever has more machines and calculates faster can mine more coins.

But now? Whether they mine is no longer the key issue. What matters is when to turn on, when to shut down, and when to sell electricity back to the grid.

Put plainly, miners are becoming temporary workers for the power grid. The real quiet winners are the energy companies that control power dispatch.

The moment miners shut down, the electricity they saved was sold to residents at high prices. Where the spread ended up is not hard to see.

Miners think they are doing arbitrage. In reality, they are just pieces on the board of energy giants.

When the core competitiveness of crypto mining shifts from “who has stronger computing power” to “who reads power prices better,” the underlying logic of Bitcoin mining has already changed quietly.

We may need to reconsider the question: in an era of increasingly scarce energy, is Bitcoin’s moat really those strings of complex hashes, or the pitiful scraps of surplus electricity that can be cut off at any moment?

The cold snap will eventually pass. But the struggle between energy and freedom has only just revealed the tip of the iceberg.
