币界网报道:Cryptocurrencies relinquished most of their overnight gains during midday U.S. trading on Monday as Bitcoin dropped below $100,000 following reports of Iran's potential attack on U.S. bases in the Middle East. Ethereum's Ether fell under $2,200, and XRP dipped below $2, though Bitcoin later recovered slightly above $100,000 after hitting a Sunday low near $98,500. The market downturn coincided with Axios' report that the Trump administration anticipated Iranian retaliation for U.S. airstrikes on three nuclear sites, prompting an emergency meeting with the national security team.
