Recently, Bitcoin's global hash rate has significantly declined within just a few days, sparking widespread speculation on X. Many believe that this sharp drop in hash rate may be related to the U.S. airstrikes on Iran's nuclear facilities on June 22.

Iran is considered one of the major countries for Bitcoin mining. In 2019, the Iranian government legalized mining and issued licenses to operators. Iranian miners utilize cheap electricity provided by fossil fuels and nuclear power for mining. Iran once accounted for 4.5% of the global mining share, although it has now decreased to about 3.1%.

The U.S. bombing may have targeted the power infrastructure near Iran's main mining facilities. Following the escalation of tensions, reports have emerged of power outages and internet disruptions in both Iran and Israel. This implies that Iranian miners have been affected, whether through actual destruction or power outages.

While it is unclear whether the destruction of Bitcoin mining was a deliberate target of this attack, it is likely a collateral effect caused by damage to the energy system. According to Al Jazeera, the U.S. attack on Iran's nuclear facilities (including Fordow, Natanz, and Isfahan) on June 22 caused damage to power infrastructure, such as the critical power infrastructure at Natanz (like substations, main power buildings, emergency power supply, and backup generators), which may have led to mining machines going offline. $BTC #以色列伊朗冲突
