#bar There is no worst, only worse. When I exchanged bar with usdt, I exchanged more than 14,000 u. At that time, the market price was 1 bar≈2.4 u. The free exchange system directly deducted more than 2,000 u after the exchange. When I contacted customer service, they said that the market fluctuations gave me a price of 1 bar≈3 u. If I don't accept it, they will cancel my qualification to contact manual customer service.
