When buying flight tickets on Ctrip and paying with a credit card linked to Alipay, I was surprisingly assessed as a risk. Moreover, I received calls from the local police station in both my original and current residence, asking if I had been scammed and requesting me to meet in person to explain the situation. There is evidence to support this. I haven't made any transactions involving U in the last few months, nor have I traveled abroad; I just bought a ticket for a family member returning from New Zealand. I really didn't know the situation had become so tense. It's quite unbelievable. I was planning to buy a large amount of U, but now it seems I can only buy it in person offline #冻卡问题 #USDT #支付宝限制
