On January 26, Winter Storm Fern caused a significant drop in U.S. Bitcoin mining power, removing approximately 200 EH/s from the network. Foundry USA’s hashrate plunged around 60% to ~139 EH/s from ~328 EH/s, while Luxor fell to ~26 EH/s. The weather disruption extended average block times to roughly 12.4 minutes and is projected to trigger a ~15% decrease in Bitcoin’s mining difficulty at the next adjustment.
