How to compensate if there is no transaction money?

This exchange is really amazing now!\n\nThis is an account that a fan asked me to look at. If I don't mention what happened later, everyone might think it's quite normal, just an account that lost 800,000 U.\n\nNote: But this account was deliberately manipulated and liquidated by a certain exchange yesterday and the day before. Now this fan says, "The losses can be seen, but we can't see any of his recent trading records, nor the records of being deliberately stopped out and liquidated. Even the weekly and monthly returns show no trading records at all." Then he contacted the exchange's customer service, but the customer service confidently told him: You have not had any trading records recently.\n\nSince this fan's real-life situation is okay and he doesn't lack this little bit of money, he is very dissatisfied. So he is preparing to take corresponding countermeasures through some of his resources, and I will update the results later.\n\nDo you all know which exchange it is? 😂\n\n#比特币打破感恩节魔咒 $BTC \n
