In a single second, more than 4,000 BTC traded in one contract. Seeing that number, my first reaction wasn't "who got liquidated?" but "just how thin is this market's depth?"

Liquidations are never a matter of someone's personality; they're a checkup on liquidity. What you see is a long wick. What the exchange sees is an order book emptied in an instant.

So don't treat other people's liquidations as gossip. They're really a risk report written for you.
