Bitcoin Mining Difficulty Has Never Stayed Below Its Peak for This Long

Bitcoin’s mining difficulty has now spent 374 days below its October 2025 all-time high, the longest such stretch in the network’s history, beating a record set after the 2011 crash. Economist and author Saifedean Ammous flagged the milestone on Saturday, writing that Bitcoin difficulty has been below its all-time high for more than a year , adding: Difficulty is the measure of how hard it is to find a new block. The network adjusts it about every two weeks, or every 2,016 blocks, so that blocks keep arriving roughly every 10 minutes no matter how much computing power is pointed at the chain. Bitcoin.com News checked the claim against Mempool.space data and found that the difficulty quotient set its record of 155.97 trillion (T) at block 921,312 on Oct.
