They wait for you to start trusting them and invest a large amount, after which they zero out your funds. Customer support took 1 bitcoin (I invested $6000). When trying to withdraw money, the account freeze didn’t help — the funds just disappeared. Support said that the email was hacked, but after changing the password, no one could withdraw money for at least a day. Good luck to everyone! Protect your funds and carefully study the agreement with exchanges; this will immediately give you an understanding of the situation.
