Do you mean you can buy wealth management products by credit card? If so, it won't work. You must have a non-credit card, such as a debit card or a financial card. Broadly speaking, credit card itself is a way of managing money. For example, if you buy things by credit card instead of paying in cash, you can enjoy an interest-free period of 20-50 days or even longer, during which your cash can be managed to earn interest. Credit cards can also be exchanged for gifts, so clever use of credit cards can also bring benefits. Hope to adopt me, thank you ~!
