The complexity of Bitcoin mining has decreased by 10.09%, to 124.93 T. This was the biggest drop since early February, when it collapsed by 11.16% amid winter storms in the United States. Since the beginning of the year, the complexity has decreased by almost 16% from the start-up of 148.26 T and declined by about 20% from the historical maximum of 155.27 T recorded in October 2025.

The network’s average hash rate fell to 740 EH/s, and the interblock interval increased to 12 minutes (while the smoothed seven-day hash, according to Glassnode, remains at 888.4 EH/s). According to TheEnergyMag, the decline is due to several factors: a flawed price of Bitcoin itself, summer heat in Texas, where miners are turning off balancing equipment, and the continued shift of some capacity to computing for AI.

For the remaining miners in the network, the collapse of difficulties was a positive factor: heshprais (profitability) rose from $29.4 to $32.7 per PH/s per day. This decline is borne out by recent Oncheen data on the surrender of miners, who have been forced to optimize their business models and look for alternative sources of revenue amid declining margins and rising operating costs.
