Bitcoin Miner Capitulation Could Be Biggest Since 2021

Key Points

• Bitcoin’s hashrate fell over 40%, largely driven by temporary U.S. weather-related power curtailments.
• Current conditions differ from 2021, with miners remaining operational and financially adaptive.

The Bitcoin network has experienced a notable hashrate decline since its September 2025 peak, prompting discussion about potential miner capitulation.

Hashrate measures the total computational power securing the Bitcoin network and is commonly used to assess miner activity levels.

Drivers behind the recent hashrate decline

After reaching an all-time high above 1.28 ZH/s in September 2025, Bitcoin’s hashrate fell to roughly 676 EH/s by late January 2026.

The sharpest reduction occurred between January 22 and January 25, coinciding with the North American winter storm known as Winter Storm Fern.

Extreme cold increased electricity demand, leading grid operators to request large industrial consumers, including miners, to temporarily reduce usage.

Several major U.S.-based mining pools, including Foundry USA, scaled back operations, contributing to longer block times until difficulty adjustments were applied.

These reductions were largely voluntary and aimed at stabilizing regional power grids rather than signaling permanent shutdowns.

Comparison with the 2021 hashrate collapse

In 2021, Bitcoin’s hashrate dropped by roughly 50% following China’s nationwide ban on industrial Bitcoin mining.

That event forced miners offline abruptly and required large-scale physical relocation of mining equipment to other countries.

By contrast, the 2026 decline reflects temporary operational adjustments, with miners able to resume activity once grid conditions normalize.

U.S.-based miners have increasingly adopted flexible energy strategies, including selling electricity back to the grid when prices are favorable.

Reports indicate that some miners increased profitability during the storm by prioritizing energy sales over block production.

Additional revenue diversification, including co-locating AI workloads alongside mining infrastructure, has further reduced operational risk for miners.

While hashrate volatility has prompted comparisons to 2021, the underlying causes and miner responses suggest a structurally different environment.
