Let’s talk about the U card logic first: USDT → transfer to U card → spend/withdraw ¥

The biggest fear when withdrawing funds is receiving black money. Once your card is frozen, it is very difficult to unfreeze it. Friends who have experienced it know it well.
Uncle hats everywhere generally have a negative impression of parties involved in the purchase and sale of virtual currencies. Even if the party whose card is frozen is innocent, when communicating with the public security agency to unfreeze the bank card, he will be required to "refund the victim's involved money" as the reason for unfreezing. Prerequisites, and even worse, they will be labeled as "crime of aid" and "crime of concealment"
