US Bitcoin miners cut output during Winter Storm Fern as network hashrate dips

ambcryptoPublicado em 2026-01-26Última atualização em 2026-01-26

Resumo

US Bitcoin mining companies, including CleanSpark, Riot Platforms, Marathon Digital, and Iris Energy, significantly reduced their daily bitcoin production during Winter Storm Fern. The extreme weather strained regional power grids, prompting miners enrolled in demand-response programs to temporarily scale back operations to prioritize residential and critical infrastructure electricity needs. On-chain data confirmed synchronized output declines, with hashrate dropping from over 1 trillion to around 760 billion. The Bitcoin network’s difficulty adjustment mechanism absorbed the temporary reduction in mining activity without affecting security or block production. The curtailments highlight the industry’s role in supporting grid stability during periods of stress.

Several major US Bitcoin mining companies sharply reduced daily production as Winter Storm Fern swept across large parts of the country. The storm placed pressure on regional power grids and prompting energy-intensive operators to curtail load.

The winter storm forced grid operators to prioritise residential and critical infrastructure demand.

In response, Bitcoin miners participating in demand-response programmes temporarily scaled back operations, according to on-chain production data.

Bitcoin mining rate declines

Figures compiled from CryptoQuant show a marked decline in daily bitcoin output across several publicly listed miners.

CleanSpark’s production fell from roughly 22 bitcoin per day to around 12. Riot Platforms saw output drop from about 16 bitcoin to just 3.

Marathon Digital recorded a sharper swing, from approximately 45 bitcoin to 7, while Iris Energy declined from around 18 to 6.

The reductions were abrupt and broadly synchronised, suggesting deliberate curtailments rather than operational failures or changes in mining economics.

US-based miners, particularly those operating in deregulated power markets such as Texas, commonly agree to reduce electricity consumption during periods of grid stress in exchange for financial incentives or longer-term power cost advantages.

Bitcoin hashrate data confirms temporary curtailment

An analysis of network-level data supports this interpretation.

Bitcoin’s hashrate dipped noticeably during the same period as the production declines before beginning to recover. This indicates that multiple miners simultaneously reduced their activity.

CryptoQuant data showed that the hashrate fell from over 1 trillion to around 760 billion, as of this writing.

While daily hashrate figures are inherently volatile, the timing and short duration of the decline closely align with the peak of the winter storm and the associated grid disruptions.

What this means for Bitcoin

Short-term hashrate fluctuations during extreme weather events are consistent with Bitcoin’s operating history and protocol design.

The network’s difficulty adjustment mechanism is designed to accommodate temporary changes in mining power, recalibrating over time to maintain stable block intervals.

In this instance, the data suggests that Bitcoin’s security and functionality were not materially affected.

Miners curtailed operations to support grid stability during Winter Storm Fern, then began restoring capacity as conditions normalised, highlighting the network’s ability to absorb short-lived external shocks.

Final Thoughts

  • The recent drop in miner production reflects weather-driven grid curtailments during Winter Storm Fern, not structural weakness in Bitcoin mining.
  • Network hashrate data shows the Bitcoin protocol absorbed the disruption without lasting impact on security or block production.

Attention, Bitcoin Users! Today's Hack May Be Larger Than You Think. Here's What to Do

Bitcoin users are urged to take immediate action following the disclosure of a critical security vulnerability. Hardware wallet manufacturer Coinkite has revealed a flaw in the seed phrase generation process for certain Coldcard Mk3 devices running firmware versions 4.0.1 through 5.0.3. All bitcoin addresses created from seed phrases generated on these potentially affected devices are now considered at risk. This warning coincides with an ongoing investigation into a major hack that drained approximately 1,082.65 BTC (worth roughly $70.2 million at the time) from 1,196 single-signature wallets in just 41 minutes on July 30. Security analysts believe the coordinated thefts, which used identical transaction fees and left no change, were executed by an automated tool scanning for compromised private keys. Notably, this attack occurred about 30 hours before Coinkite's public disclosure of the Coldcard vulnerability, raising concerns of a possible connection. Experts strongly recommend that impacted Coldcard Mk3 users do not consider their old seed phrase safe. The advised course of action is to generate a completely new, secure seed phrase on a trusted, modern hardware wallet and then transfer all funds to addresses derived from this new seed. Simply moving the old, potentially compromised seed to a new device is not sufficient.

Bitcoin in August: Experts Expect Range Testing, Not a Quick Reversal

Experts anticipate Bitcoin will remain under pressure in August, lacking momentum for a sustained rally after a partial July recovery. The price, trading around $63.5k, is seen stuck in a $60-65k range. Analysts cite a challenging macro environment of high U.S. rates, persistent inflation, and a strong dollar as key headwinds, alongside record ETF outflows. Historically, August is a weak month for crypto. Experts outline three main scenarios: a base case of sideways movement between $58-68k (50% probability), a bearish drop to $50-55k (30%), or a bullish push toward $71-75k (20%). Key levels to watch are support at $60-61k and resistance at $67k. While some see current prices as attractive for long-term accumulation, most warn of potential short-term downside, with a retest of $60k or even a fall toward $53k possible. A decisive market turnaround is not expected before Q4, making August a month for testing key levels rather than a major breakout.

Coldcard Hardware Wallet Hacked: 594 Bitcoin Withdrawn in 25 Minutes

The Coldcard hardware wallet has been compromised, with hackers stealing approximately 594.5 Bitcoin (~$40 million) from 500 addresses in just 25 minutes. The root cause was a critical software bug, undetected for five years, which disabled the device's secure chip for generating true random numbers. This led to the creation of private keys based on predictable data like the processor's serial number, drastically reducing cryptographic security. The attackers exploited this offline by brute-forcing possible seed phrases, finding active addresses on the public ledger, and signing transactions. Initially, Coinkite (Coldcard's maker) claimed only older models were at risk but later admitted all devices running the compromised firmware were vulnerable. CEO Rodolphe Novak (NVK) apologized but ruled out financial compensation for affected users. To secure funds, owners must urgently update their firmware to specific safe versions, generate a completely new seed phrase on the updated device, and transfer all assets to new addresses created with that new seed. While a BIP-39 passphrase can help, it does not replace this migration process. Other Coinkite products like TAPSIGNER were not affected. This incident underscores that even specialized hardware requires rigorous, independent code audits, especially for cryptographic functions. It parallels past failures, like a 2006 OpenSSL bug in Debian, and raises questions about whether automated code analysis can ever fully replace human scrutiny in critical security areas.

Circle Reaches Major Regulatory Milestone, Receives Trust Charter from New York Department of Financial Services (NYDFS)

Circle, a financial services and stablecoin company, announced it reached a key regulatory milestone by receiving a Limited Purpose Trust Charter from the New York State Department of Financial Services (NYDFS). This charter allows Circle to expand its operations in New York to include asset custody services, issuance of NYDFS-approved stablecoins, and management of the reserves backing them. The approval positions Circle's USDC stablecoin within a regulated framework and follows the company's earlier receipt of a national trust bank charter from the U.S. OCC. CEO Jeremy Allaire stated this achievement reflects over a decade of compliance commitment and aligns with NYDFS's high standards, comparable to those for full commercial banks, as digital dollars become central to the global financial system.
