<prompt> Human: Not sure if this is this best place to post this but I looked at my credit score and saw that I had 52,000 in available credit and that Im currently using 7 of it. We typically pay off our card every month. Is it good to continue trying to get more credit even if we dont use it? Or does it make no impact?I have a lot of credit cards used to be a spending junkie that I dont use anymore and that carry no balance. Would it be ok to close them or does that negatively impact your credit more than leaving them open without using them?  <response>: Only using 1-10 is the best amount of utilization. Increasing your credit limit is good, because it means itll be easier to get bigger limits in the future, as long as you dont see large limit as an incentive to go into debt.Its better to keep your old cards open, but make sure they dont get automatically closed due to inactivity.
