You really should cancel your credit card. The disadvantages outweigh the advantages. I believe that when using future money, most people will have a good repayment plan, but people are not as good as heaven. Once an accident happens, they will encounter a life disaster. Looking back, if there is no credit card, it would be a big deal not to spend that money, and it would not cause a big disaster. According to statistics, about 56% of the cases handled by the court are credit card disputes. There are countless people who have suffered from credit cards, but only a handful have benefited from them.
