Three altcoins are facing significant liquidation risks this week following a record $19 billion crypto liquidation event. Ethereum's open interest has dropped from $63 billion to $48 billion as traders adopt a cautious stance amid bearish market sentiment. BNB has surged to a new high, but it faces potential liquidations exceeding $300 million if its price retraces to $1,150. Meanwhile, ZEC has shown resilience with balanced long and short positions, yet it could see $20 million in liquidations if it breaks above $315, and $17 million if it falls to $227.
