The specific operation method is to set aside some spare money after paying wages every month, use the remaining money to buy money market funds, and try to swipe your card at ordinary times, so that you can not only urge yourself to develop good financial management and savings habits, but also gain income. The cardholder can set the redemption date of the fund two days before the credit card repayment date, which is equivalent to using the redeemed fund money to repay the credit card. At present, the yield of money market funds is around 2%, but it is still much higher than the current savings of banks. Earn the difference between the two on the redemption date of the fund every month and obtain indirect monetary income.
However, investment funds have certain risks after all. If you buy a fund in this way, you must consider your repayment ability to avoid being fined by the bank because of insufficient repayment ability and overdraft exceeding the credit limit.
