Brothers and sisters playing U, listen up! In case one day you are invited by the 👮 'uncle' for tea, don't panic. Basically, there are three hurdles to consider:

The first hurdle is the intimidation tactic: "Virtual currency is not protected by law, do you know that? Don't get confused by the questions, this matter needs to be explained step by step. Just because the law does not protect it, doesn't mean you are breaking the law. It means that your transaction is consensual, and no one will interfere; but if something goes wrong, for instance, if you are scammed, the police uncle can't help you recover your coins. So, you should openly admit that you understand this risk and are willing to bear it yourself.

The second hurdle is the core issue: "If the money received is dirty money, why should you return it?" Remember, this is not a negotiation, it's a necessary procedure. Once the money reaches your account, as long as it is classified as fraudulent funds, you must cooperate with the return process. How much to return and how to return it has some operational flexibility. You can discuss with the case handlers and even communicate directly with the victims. As long as you reach an agreement, your bank card may have a chance to be unfrozen. Don't stubbornly resist; it's a total waste of effort and meaningless.
The third hurdle, which is also the most concerning: "Will not cooperating leave a record? Can other cards still be used?" As long as your attitude is sincere, and the submitted materials are complete, proving that your funds are clean, you usually won't be left with a record, nor will it affect the use of your other bank cards.
But there is a key point that must be clearly understood:
Level 1 involved card: This is the worst situation, equivalent to being blacklisted by the bank and public security system, and all bank cards under your name may be implicated and have issues.
Level 2 involved card: The impact is much smaller, mainly freezing this involved bank card without implicating other cards.
Finally, let me emphasize: Playing U is essentially dancing in a gray area; don't take it as simple as shopping on Taobao. Regardless of the size of the transaction, the other party's information and the source of funds must be thoroughly checked and clarified. Remember this: Do not touch money of unknown origin. Don't sacrifice your account and reputation for a small profit; that would be a real big loss.
