Internet reports that recently, Bitcoin's global computing power has dropped sharply in just a few days, triggering widespread speculation on the X platform. Many people believe that this sharp drop in computing power may be related to the U.S. air strike on Iran's nuclear facilities on June 22. Iran is considered to be one of the major Bitcoin mining countries. In 2019, the Iranian government legalized mining and issued licenses to operators. Iranian miners use cheap electricity provided by fossil fuels and nuclear power to mine. Iran once accounted for 4.5% of global mining, although it has now dropped to about 3.1%. The U.S. bombing may have hit power infrastructure close to Iran's main mining facility. After tensions escalated, there were reports of power outages and network outages in both Iran and Israel. This means Iranian miners were affected, whether through actual damage or through power outages. Although it is unclear whether disrupting Bitcoin mining was a deliberate target of the attack, it is likely a side effect of disrupting the energy system. According to Al Jazeera, the June 22 U.S. attack on Iran's nuclear facilities, including Fordow, Natanz and Isfahan, caused damage to power infrastructure, such as the destruction of critical power infrastructure in Natanz (such as substations, main power buildings, emergency power supplies and backup generators), which may have led to the rolling off of mining machines.
