You can't pay for the fund by credit card. Credit cards are mainly used for consumption, while funds belong to investment and wealth management. Investment and financial management are risky, and credit card funds are not allowed to enter the securities market. You can only use a debit card to buy funds, not a credit card.

Credit card is a credit certificate issued by commercial banks or credit card companies to qualified consumers. Consumers with credit cards can go to specialized commercial service departments for shopping or spending, and then the bank will settle accounts with merchants and cardholders, and cardholders can overdraw within the prescribed limits.
