Bitcoin Hashrate Rebounds from 850 EH/s Support

Bitcoin's hashrate has shown signs of recovery after repeatedly finding support near 850 million TH/s. The network computing power rose to 915 EH/s on September 8, but remains below its October 2025 peak of about 1.15 ZH/s. Despite the latest rebound, the current computing power is roughly 20% beneath the previous high.

The hashrate fell by about 20% during a disruption caused by severe U.S. winter storms in early 2026. Power costs remained high in several mining regions after the storms, and some Bitcoin miners redirected their infrastructure toward AI and high-performance computing operators due to increased competition for electricity.

Bitcoin's difficulty adjustment mechanism helped offset weaker mining conditions by reducing mining difficulty and making it easier for remaining miners to earn rewards. This allowed active miners to capture a larger share of block rewards using the same equipment, partially offsetting the drop in network activity.

The recent recovery has shown signs of improvement in miner economics, with hashprice estimates near $40 per PH per day, up more than 22% from previous levels. Growing revenue alongside stable hashrate could reduce the financial pressure that forces miners to shut machines down or sell Bitcoin to cover operating expenses.
