<prompt> Human: I saw someone on this subreddit mention that you should use your old card every few months. Is there actually any benefit to doing this, as opposed to just having the credit card open? I dont use my oldest cards as there are no rewards, and I never carry a balance on anything, etc.I tried searching, but its actually quite difficult to word this question properly, sorry if its simple.  <response>: Most banks will purge their inactive credit card accounts after a while. I was sent a warning once after 5 years that one of my cards would be closed due to inactivity. So youll have to use the card once in a while to keep the line open, but in the end, your goal is just keep it open.
