A major BTC short seller is feeling the heat. This whale, sitting on roughly $225.8M in short positions spread across $BTC, $ETH, $SOL, and $SUI, just watched their paper profits evaporate. The PnL swing is brutal—they went from +$7.7M in gains to -$1.7M in losses, now nursing over $6M in unrealized losses as the rally keeps pushing against their bets. When you're holding that much short exposure and the market's moving the other way, every hourly candle becomes painful to watch.
