Bitcoin Mining Power Surges Past 1 Teraexahash

Bitcoin's mining network has reached an unprecedented milestone: a total computing power of nearly 1,001 exahashes per second (EH/s), just shy of the zettahash threshold. This is up from 883 million terahashes per second (TH/s) just a year ago, with hash rate growing steadily since then.

The mining difficulty, which adjusts every two weeks to keep block production consistent, has fallen nearly 20% from its all-time high in October 2025. This drop in difficulty means that miners are now earning roughly 24% more BTC per terahash of computing power, making it a crucial factor in their profitability.

The key metric here is hashprice, which measures the revenue earned by miners per unit of hash power per day. By late August 2026, hashprice estimates had recovered to around $38 per petahash per second (PH/s) per day, up from a low of $27.66 in June.

This resurgence is significant for miners who survived the June squeeze, as it marks a real reprieve rather than just a headline number. However, hashprice recovery doesn't automatically mean fatter margins for everyone, as costs such as electricity contracts and cooling overhead remain a major concern.
