Update (2-7-2026): Latest BTC Difficulty Projections
The Bitcoin network has recorded a steep mining difficulty decline, falling roughly 11.16% in the last 24 hours. This marks the largest single-period drop in mining difficulty since China’s 2021 crackdown on crypto miners. Bitcoin (BTC) traded near $71,381 as the network adjusted, with the new difficulty level set at 125.86 T after block 935,429.
What changed in the latest difficulty adjustment
Mining difficulty, the protocol metric that measures how hard it is to find a new block, dropped to 125.86 trillion (T) and took effect at block 935,429, according to CoinWarz. Average block time tightened to about 9.47 minutes, slightly faster than the 10-minute target. Short-term estimates show difficulty is likely to rebound at the next adjustment on February 20, with CoinWarz projecting a ~5.63% rise to about 132.96 T.

Why the drop matters for miners and the network
A rapid reduction in mining difficulty typically signals a decline in total hashrate — the aggregate computational power securing Bitcoin. Reduced hashrate can come from miners powering down rigs due to economics, power outages, or relocating operations. When hashrate falls, difficulty adjusts downward to preserve the average block time and keep block issuance steady.
Historical context: echoes of the 2021 China ban
The last time the network saw comparable single-period drops was during China’s 2021 mining ban, when difficulty fell between 12.6% and 27.9% during May–July 2021 as miners were forced offline or moved operations overseas. That era also coincided with a broader crypto market downturn that pushed Bitcoin far below its highs and squeezed miner margins.
The disruption to the power grid caused US-based Bitcoin miners to temporarily curtail their energy usage and halt operations, reducing the total network hashrate, the amount of computational power expended by miners to secure the Bitcoin protocol.
Large areas of the United States experienced power outages and service disruptions during winter storm Fern.

This recent difficulty drop was amplified by severe winter weather in the U.S. that disrupted electricity supply and forced many operations to curtail energy use. Foundry USA, the world’s largest mining pool by hashrate, reportedly lost roughly 60% of its hashing power during the storm, falling from nearly 400 EH/s to about 198 EH/s at its nadir.

Recovery and shifting mining dynamics
Foundry’s hashrate has since rebounded to over 354 EH/s, maintaining a roughly 29.47% market share, per Hashrate Index. Despite recovery at some major pools, total network hashrate fell to a four-month low in January amid weak crypto market conditions and several miners repurposing infrastructure for AI and other high-performance computing workloads.
Market and mining outlook
Short-term, miners face higher operational pressure when Bitcoin prices and realized margins compress. A downward difficulty adjustment briefly lowers competition but also reflects the fragility of hashrate concentration and regional power risks. Looking ahead, the projected increase in difficulty on February 20 suggests hashrate is likely to stabilize as miners bring rigs back online or deploy capacity elsewhere.
For traders and institutional observers, sudden difficulty swings underscore how external factors — weather events, regulatory shifts, and industrial migration to AI — can influence Bitcoin security, mining economics, and, indirectly, price dynamics. Expect closely watched hashrate and difficulty updates to remain key indicators for market participants.
