Bitcoin has fallen below the $80,000 mark amid a sharp market-wide sell-off, with major altcoins also breaching key support levels. Ethereum dropped under $2,350, Solana fell below $100, and XRP declined to under $1.30. The rapid price decline triggered significant liquidations in the derivatives market. Over $200 million in leveraged long positions were forcibly closed within just 60 minutes as traders faced mounting losses across the board.
