Bitcoin Mining Difficulty Stays Below Its ATH for 374 Consecutive Days, Setting All-Time Record Bitcoin mining difficulty has spent 374 consecutive days below its all-time high of 155.97 T (set on October 29, 2025), officially marking the longest stretch in the networks history and surpassing the previous record of 364 days from the 2011 crash. As well as the gap of 253 days after the 1 minute ban in China 202. The prolonged rally is being driven by muted BTC price action (~$76,000) and increasing overhead, prompting publicly listed miners to liquidate Bitcoin reserves and turn the ether's power towards AI sharing. - Link.
