A certain major exchange is currently facing serious risk control issues, but I won't say which one for now. A few days ago, my own account made money, and I also helped operate some accounts of the bosses to recover tens of millions of dollars. However, when I tried to withdraw, they put me through 24 hours of risk control, claiming that there were unusual fund movements. This is still the case for a top-tier exchange, making tens of millions of dollars, and it turned out like this. At that time, the position was 70,000 ETH.
