A certain major exchange now has serious risk control issues, I won't say which one for now. A few days ago, I made money on my own account, and I also operated some bosses' accounts to recover tens of millions of dollars. Then, when I wanted to withdraw, they put me under 24-hour risk control, saying that the fund movements were abnormal. This is still a leading exchange, and even if you make tens of millions of dollars, it ends up like this. At that time, my position was 70,000 ETH.
