I have been, they added me to a Zalo group, bragging about profits, sharing trading signals through the Binande app, and then manipulating prices, and my account has burned every time.

Warning to those buying USDT on the exchange.
Please avoid this USDT purchase account.
I bought 5 million but the account forced me to befriend on Zalo to unlock USDT, and when the 12-minute deadline was up, they still wouldn't unlock it. I had to ask the exchange to intervene before they finally unlocked it.
