Due to the U.S. military airstrikes on Iranian nuclear facilities in late June, which affected the power system, mining activities in Iran significantly declined, with the country accounting for over 3% of the global share. The interruption of cheap electricity caused mining machines to go offline, and although it was not directly aimed at mining, it exposed the potential vulnerabilities of the Bitcoin network in geopolitical conflicts.

Data from CoinAnk shows a significant decline in total network computing power of 10,431,813,177 in late June 2025. In the short term, the decrease in computing power may weaken transaction confirmation efficiency and impact security, but historical experience indicates that mining difficulty adjustments will attract miners back, restoring relatively quickly.

Such events highlight that while Bitcoin's decentralized characteristics are resilient, they are easily affected by external disturbances. For the cryptocurrency market, BTC prices are under short-term pressure, falling below $100,000 and triggering large-scale liquidations; however, the rise in mining company stock prices reflects the market's recognition of system resilience. A rebound in risk appetite in the Middle East may bring buying opportunities, but investors should be wary of sustained volatility caused by escalating conflicts and avoid leverage risks. Overall, the long-term trend of BTC still depends on fundamentals rather than a single geopolitical event.
