ビットコインは63,000ドルに迫るが、イランの戦争で再び下落

The drop extends a pattern where bitcoin sells off on geopolitical shocks before recovering, as the token's 24/7 liquidity makes it one of the few large assets traders can exit over the weekend.Updated Feb 28, 2026, 3:05 p.m. Published Feb 28, 2026, 6:56 a.m. Bitcoin briefly reclaimed $65,000 before pulling back to $64,700 as the Iran conflict continued to escalate through Saturday.Iranian state media reported at least 70 killed in its Hormozgan province, per Aljazeera, including a strike on an elementary school. Israel activated air raid alerts after detecting fresh missile launches from Iran.Trump told the Washington Post that "all I want is freedom for the people."

Bitcoin trades 24 hours a day, 7 days a week, while equity and bond markets are closed on weekends. That makes it one of the only large, liquid assets available for traders to sell when geopolitical risk spikes outside of traditional market hours. The result is that bitcoin often acts as a pressure valve for broader risk-off sentiment during weekend events, absorbing selling that would otherwise spread across equities, commodities, and currencies if those markets were open.The attack risks a wider regional conflict in one of the most economically sensitive parts of the world, following a month-long U.S. military buildup and failed negotiations over Iran's nuclear program.More For YouCrypto community fear of Iran choking oil supply and crashing markets may be overblownA full closure of the strait is unlikely or impractical, some experts argue.What to know: Many crypto social media users on X worry that Iran could close the Strait of Hormuz, a key route for about 20 percent of global oil shipments, potentially sending oil prices toward $120 to $150 and triggering an inflation shock.Several experts argue that a full closure of the Strait is unlikely or impractical and that any oil price spike would likely be limited and temporary.
