Bitcoin broke below the $81,000 level today, hitting $80,992—a 2.9 percent decline over 24 hours.

The move triggered a cascade of liquidations across derivatives markets. Over $400 million in leveraged long positions were wiped out within an hour, according to on-chain data. As collateral fell below maintenance margins, exchanges automatically closed positions, amplifying selling pressure.

Ethereum dropped 5.3 percent to $2,433, while Solana fell to $108.61, showing correlated weakness across major digital assets.

The Crypto Fear & Greed Index remains at 64—neutral to greedy territory—suggesting underlying conviction has not cracked despite the deleveraging event. For traders, this is a reminder that leverage at key technical levels remains dangerous. Position sizing and stop discipline matter when psychological price points trigger cascade liquidations.
