First of all, one advantage of credit card is that it is convenient to borrow money. As long as you have enough credit, you can get cash support quickly without borrowing from others when you are short of money. When there is no money to spend, it can be treated as an emergency. As long as you hold a credit card, you can spend in advance.

As a result, you can't repay on time within the repayment date, which brings you the trouble of credit fracture.
