BingX hacked, $43 million stolen

Maybe they have variable withdrawal fee now, or they are trying to earn more money from fees to recover from recent hack
Transaction fees was low for days during this jump in Bitcoin price, but today we can see more transactions in mempool with 31 sat/vB or around $4.

I think the reason would be the increase in the transaction fee as a result of mempool congestion. It was BingX that was hacked and not Mexc. I guess you thought I was referring to BingX.
