Bitcoin Hashrate Rebounds to Its Highest Level Since March 3

Bitcoin’s estimated seven-day average hashrate climbed above 1,000 exahashes per second, reaching its highest level since March 3 as public miners’ own realized computing power declined.

The network had already crossed that threshold earlier in October. Its seven-day average stood at 1,031.61 EH/s on Oct. 17. The latest comparison marks the highest level since March 3.

The network-wide rise contrasts with the first-half figures for publicly traded miners. Their realized hashrate fell 56 EH/s, or 15%, while the broader Bitcoin network’s hashrate declined 10%. Comparable miners’ revenue from high-performance computing and artificial intelligence rose 52% from the first quarter to the second.

Bitdeer’s self-mining hashrate reached 82.3 EH/s in September, up from 79.9 EH/s in August and 35 EH/s in September 2025. Its co-mining hashrate rose to 28.7 EH/s from 21.6 EH/s in August.

“That’s hardly the breathing room remaining miners might have expected from the AI migration,” BlocksBridge Consulting wrote.

Bitcoin mining difficulty increased 5.92% to about 140.58 trillion at block 971,712 on Oct. 16 at 8:37 a.m. ET (12:37 UTC). The adjustment followed the latest 2,016-block interval. Bitcoin recalculates difficulty at those intervals to keep blocks arriving at roughly 10-minute intervals on average.

Hashrate estimates infer network computing power from block creation and the difficulty setting; they do not directly count miners’ machines. Random block discovery can move daily estimates, while a seven-day average smooths some of those fluctuations. The network-wide figure does not identify which operators supplied all the computing power behind the rise, or show whether individual miners’ economics improved.
