The first time I bought coins was fine, but the second time I bought 100,000 dollars, my money and account were frozen, and I was not allowed to transfer or withdraw coins. I can contact customer service only by email and replying one email a week. It is a complete waste of time. Now there is no reply, the exchange has disappeared directly, and the money is not allowed to move. Every time the exchange requested something, it was uploaded, but there was no response. It is always like this!
