I clearly still have over 700 USDT. Yet I am told my margin is insufficient. The trader also has over 700 USDT. In the end, the trader made a profit of 500 USDT, while I earned less. Most importantly, the trader lost 275 USDT on the first few trades, which ultimately led to my loss of 275 USDT. Meanwhile, the trader made a profit of over 100 USDT. The trader's followers also show a loss of over 300 USDT. Is this how Binance treats its users? Even when contacting customer service, they are unwilling to provide compensation.
