木曜日のビットコイン価格は、米軍によるイランへの新たな空爆で地政学的リスクが高まり、暗号資産市場で売りが殺到したことを受け、6週間ぶりの安値となる7万3000ドルを割り込んだ。現物ビットコインETFからは大幅な資金流出が見られ、ブラックロックのIBITだけで1日に5億2800万ドルの流出を記録した。この動きは、デリバティブプラットフォーム全体で10億ドル近くの強制決済が発生したことと重なった。
ホルムズ海峡付近のイラン関連施設に対する米軍の空爆を受け、イラン革命防衛隊が報復を警告したことで、ブレント原油価格は1バレルあたり96ドルを超え、世界的なリスク選好姿勢が後退した。ビットコインは一時7万2792ドルの安値を付けた後、わずかに回復して7万3274ドル前後で推移しており、24時間で2.7％以上の下落となった。イーサリアムも市場全体の売り圧力に連動し、2000ドルを割り込んだ。
Xのユーザーの間では、米イラン間の緊張と記録的なETF資金流出を背景としたビットコインの7万3000ドル割れが議論された。また、5億ドル超の強制決済やブラックロックのIBITからの5億2800万ドルの流出、市場全体に広がるリスクオフ心理についても言及された。

Bitcoin drops below $73,000 after USA-Iran tensions and record ETF outflows! BlackRock sells half a billion worth of BTC in one day (largest ever). ETH at ~$2,000 with risk of $2 billion short squeeze.
Miners selling, dark pools active. Market in turmoil!#Bitcoin…
U.S. strikes on Iran near the Strait of Hormuz pushed BTC below $73k overnight — $1B in liquidations, and IBIT bled $528M, its second-largest outflow ever. ETFs sold "digital gold" hard; the bid disappears the moment real geopolitics shows up.#Bitcoin #Geopolitics #Macro pic.twitter.com/pBmXxG91Zw

US and iran started trading kinetic attacks earlier today, sending btc sliding below $73k. It triggered a massive risk-off cascade that flushed out all the overleveraged longs.
If this escalates, expect more pain, but for now it's just a brutal leverage wipeout

Bitcoin's price has fallen below $68,000 as escalating US-Iran conflicts drive volatility in cryptocurrency markets. The drop follows a US-Israel attack on Iran and recent statements from leaders on both sides, compounded by weak US jobs data. Other major coins like Ethereum and XRP have also declined.
Bitcoin surged above $80,000 for the first time since January during early Asian trading on May 4, 2026, reaching highs around $80,600. The cryptocurrency later pulled back to around $79,000 following reports of an Iranian missile strike on a U.S. warship, which the U.S. denied. Geopolitical risks near the Strait of Hormuz overshadowed strong ETF inflows supporting the rally.
