The exchange rate of USDT to RMB has dropped to around 6.87. Recently, Binance launched the USD1 savings promotion (high-yield campaign), at that time, the price of USD1 was roughly around 6.93. If you deposited the full amount of 50,000 USD1 (promotion limit) back then, converting it back to RMB now would result in a loss of nearly 3,000 yuan.
