Bitcoin(BTC) mining in Iran fell roughly 77% in one quarter, dropping the country's hashrate to about 2 EH/s amid regional conflict and tightening miner economics.
Iran Hashrate Decline
A new report from Hashrate Indexshowed Iran lost approximately 7 EH/s quarter over quarter. The decline coincided with escalating tensions between the United States and Israel on one side and Iran on the other, with airstrikes and retaliation shaking the region.
Neighboring mining hubs were not affected in the same way.
The United Arab Emirates and Oman held steady, according to the report. Iran is estimated to operate around 427,000 active mining rigs, though many older units with efficiency above 25 J/TH have been forced offline as margins shrink.
The broader network absorbed the loss without disruption.
Global hashrate remained near 1,000 EH/s, and the report described Iran's pullback as a localized event rather than a systemic threat. The U.S. still accounts for the largest share of total hashrate worldwide.

Bitcoin Mining Revenue Under Pressure
Miners across the board have been squeezed. The 30-day simple moving average for global hashrate slipped from 1,066 EH/s in Q1 to about 1,004 EH/s in Q2 — a drop of 5.8%. Hashrate Index tied that decline to falling Bitcoin prices, not energy costs or regulatory shifts.
BTC has dropped about 43% from its record high of roughly $126,000, set in Oct. 2025. That price erosion pushed hash prices to record lows and forced about 252 EH/s of marginal capacity offline, much of it tied to older hardware.
Mining power does not stay fixed in one place for long. It follows cheaper electricity, better equipment and wider margins. When those conditions disappear, rigs get switched off or shipped elsewhere — which is exactly what Iran's numbers reflect.
Bitcoin Hashrate Concentration
The U.S., Russia and China together control more than 65% of global Bitcoin hashrate, underscoring how concentrated mining power remains despite the network's decentralized design. When a smaller market like Iran falters, larger players absorb the slack with minimal impact on network performance.
Bitcoin has been volatile in recent weeks.
After sinking below $67,000 in early April, BTC surged past $72,000 on Apr. 8 following a two-week ceasefire between the U.S. and Iran. That swing illustrates how geopolitical developments continue to shape both mining conditions and price action across the crypto market.
