Of course, I will also comprehensively consider whether the billing date and repayment date of these banks are crowded together, and crowded together can not play the greatest role. It would be better if the points were scattered. As long as you look at the date of the day and use that card, you can enjoy the longest interest-free period at any time within one month.
Without a good credit card, it's all the same. You can judge for yourself according to the above situation.
For example, my investment quota is 10000, the bookkeeping date is 16, and the repayment date is 4 days; The limit of ICBC is 39,000 yuan, the bookkeeping date is 12 days, and the repayment date is 5 days. So I don't want to use the investment card. Although the billing date differs by several days, the repayment date is indeed earlier than that of industry and commerce.
