In fact, when you open an account in a domestic bank, you mainly remit money to the account of a foreign exchange company. After you make money, the foreign exchange company will remit money to you for use. It is best to use a dual-currency credit card, such as the RMB-USD dual-currency credit card of Bank of China, so that the cost of remittance is lower.

In addition, if you want to use the platform of a foreign exchange company to speculate in foreign exchange, you need to contact that foreign exchange company and open an account. This account is used to obtain the account name and password of the trading platform and has been used to log in to the platform for trading.

Simply put, just like buying a fund, you have a bank card, then you open an account with a fund company, transfer the money in the card to your account, and then use your account to buy and sell funds.

So when you go to the bank to get a card, you don't have to tell the other party that you are speculating in foreign exchange. Just make sure that this card can be exchanged for US dollars with China.
