Foreign exchange trading is illegal. Your bank card has illegal funds transferred in and out, so it is frozen. It is suggested to apply to the public security organ for thawing, and take the initiative to explain the situation.

At this time, you can only go to the bank counter with your bank card and your ID card, and then ask him to unfreeze it for you, so that your bank card can be used normally, because the bank will definitely freeze for some time. After you explain the situation, as long as there is nothing wrong with your transaction, you can unfreeze it.
