币界网报道：Crypto markets experienced a sharp reversal during U.S. trading hours, with Bitcoin dropping from $106,500 to below $103,000 before partially recovering to $103,200 (down 1.2%). Ethereum saw a dramatic 4.5% plunge to $2,372 within 90 minutes, accompanied by trading volume spiking to 800,000 ETH - eight times the hourly average. Major altcoins including Solana, Dogecoin and Cardano fell 3-5%. The sudden volatility liquidated $450 million in derivatives positions, with $387 million being long positions. While macro risks persist (including Middle East tensions), no immediate catalyst was identified for the price swing. Analysts note Bitcoin remains range-bound between $100,000-$110,000, reflecting market uncertainty between long-term bullish sentiment and short-term geopolitical risks.
