Someone borrowed my ID card to set up a bank card, and then used this card to speculate in foreign exchange. Is this illegal?
Ill-gotten wealth should not be greedy, and unknown money is not desirable. Reject him. Obviously, he can use your bank card to launder money, buy high-priced goods in installments, and even do something illegal. Bank cards belong to the real-name registration system, so no matter what happens, all debts will be borne by you.
