The second thing they should do is to report the person individually to Bybit. This can help Bybit to freeze the person's account fast. The person will still be traced and it will be good if he used his real identity document for verification so that he can be taken down.
Sometimes some of this banks knows exactly where how and when to get this people who are the true person behind such things dubious acts.
