So it doesn't matter to sell one!
As for how much to give when doing credit inquiry, of course not. Banks have grading standards, and how much money is given between certain scores is fixed. If you really want to give as much as you want, then everyone wants 1 million. Will the bank give it?
The credit card quota is not fixed and will be upgraded with the consumption of the card owner. Generally, when your card expires, you will be called to upgrade.
Of course, the premise is no bad record!
