On X (formerly Twitter), speculation is swirling after Bitcoin’s global hashrate dropped within days. Many believe the sudden dip may be linked to the U.S. airstrikes on Iranian nuclear facilities on June 22.

Notably, Bitcoin price briefly fell to $98,500 before rebounding above $101,000. Additionally, there is a sharp decline in hashrate, now down to 753.81 EH/s from 943 EH/s recorded in mid-June, which has caught the crypto community off guard.
The hashrate measures how much computing power is being used to secure the Bitcoin network. A high hashrate means more miners are active, but when the hashrate drops, it usually means some miners have gone offline.
Why Iran Matters to Bitcoin Mining
Iran is known as one of the big countries mining Bitcoin. Mining was legalized by the government in 2019 and licenses were issued to operators. Iranian miners utilize low-cost electricity from fossil fuels as well as nuclear power. Iran once held a 4.5% share of global mining, though it has now fallen to about 3.1%.
It’s highly probable. The U.S. bombing potentially hit power infrastructure close to major mining facilities in Iran. There were reports of blackouts and network disruptions from both Iran and Israel following heightened tensions. This means Iranian miners were impacted, either by actual destruction or through power outages.
It’s unclear if disrupting Bitcoin mining was an intentional target of the strike, but it’s a possible side effect of damaging energy systems.
Will the Hashrate Recover?
The Hashrate may not recover right away. Unless more strikes hit power plants or internet infrastructure, miners may slowly come back online. If the hashrate continues to decline, the Bitcoin network will automatically lower its difficulty to maintain transactions smoothly every 10 minutes.
This is not the first instance. When China banned mining in 2021, the hashrate fell significantly, but the network bounced back in a couple of months when miners migrated.
