I think many of us don't understand what liquidation is about and how it works. The exchanges don't make money from liquidation but they only make skme fractions from the process which is the fees. You see what happen to the long liquidated trades, those are shorters been settled and longer been forced closed their positions because they are out of health risk ratio.
Liquidation occurs when you're trading leveraged, shorting or longing the market
Exchanges have this valuable information
Exchanges can earn from the fees and from the liquidation itself, since they also own cryptos
If you look at the whole scenario that Bybit received loans quickly, the market is being liquidated and Bybit is making money, it's not hard to imagine what's going on
