First of all, generally speaking, every bank will have a complete set of risk control and early warning measures. If your credit card consumes all the credit lines once a month, it will be paid off at one time on the repayment date, and then it will be spent on the next billing day, and then it will go on like this. In the bank's view, this is an abnormal consumption habit, which will be observed by the wind control system, and the early warning will prompt your relevant abnormal information to the bank's system management personnel, but everyone will.
In the process of consumption, as long as everyone repays normally and does not cash out within the time limit, most banks will not reduce the amount of cards, and it is still possible to increase the amount. However, in one case, if you swipe your card very frequently and keep cashing in and out frequently, then you will definitely be banned, because the early warning system will frequently remind you of abnormal credit card records. Obviously, you are a high-risk person, so the bank will generally directly reduce the limit, freeze or seal your card. Especially the state-owned banks, with so many credit card users, you are not bad at all, so it is the state-owned banks that reduce the amount, freeze and seal the cards the most.
