A perp long that got liquidated last week lost 100% of its margin. Not because the thesis was wrong, but because the wick touched the liq price.
Now price the mirror: BTC sits at $63.7K. A 30-day $60K/$55K put spread costs about $1,000 to put on. That $1,000 is your max loss. If BTC closes at $55K or below, it pays $5K, so you net roughly $4K.
The same wick that zeroed the long was a clean, pre-sized payoff for whoever owned the downside.
