Bitcoin mining exercise throughout the U.S. is in sharp decline as an Arctic storm entrance batters a number of U.S. states, with U.S.-based operators scaling again operations to ease stress on the ability grid in the course of the troublesome interval. In consequence, Bitcoin’s community hash charge has dropped considerably, with present information exhibiting a complete hash energy of 800 to 875 exahashes per second (EH/s) over the previous day.
6-day slide: Arctic explosion drops Bitcoin hashrate by almost 250 EH/s
The Arctic storm entrance in late January 2026 will hit the South and decrease Ohio Valley the toughest, with essentially the most extreme circumstances centered on Tennessee, Texas, Louisiana, Mississippi, Kentucky, Georgia, Alabama, and West Virginia.

Nonetheless, community information compiled by hashrateindex.com exhibits that the steepest decline really occurred after January 22, 2026. On that day, the overall hashrate was measured at 1,053 EH/s and at present sits at 805 EH/s with a 3-day SMA. Actually, of the 385 EH/s lower from the all-time excessive of 1,190 EH/s on October 15, 2025, roughly 248 EH/s disappeared between January 22 and January 28.
As famous in our report, the drop in hashrate has pushed block intervals nicely past the standard aim of 10 minutes. On the time this report was revealed, the common block time was over 12 minutes and continues to hover at 12 minutes and 12 seconds. If this tempo continues, the troublesome interval that arrives round February 8, 2026 will rank as one of many largest corrections in years.
Out of the final 6 epochs, the problem has decreased 5 instances and elevated by solely 0.04% on December 24, 2025.
At the moment, hashrateindex.com and different monitoring platforms predict a discount in issue of greater than 18%. This consequence stays very believable, because the arctic storm entrance throughout the USA is anticipated to proceed into early subsequent week, bringing us uncomfortably near the approaching troublesome interval. The magnitude of the expected decline will probably diminish as soon as hashrate recovers and block instances normalize previous to the adjustment, however for now, the information factors to document issue declines.

The timing could not be higher for Bitcoin miners, who’re affected by falling BTC alternate charges and skinny hash price-based returns.
