<prompt> Human: I currently have 2 credit cards open with 5k limit on each. Im wondering if I can should open a third card for more churning after 31 days pass. How many times can I do this, and how do having these cards open negatively affect me? Im assuming Ill need to close out some of these cards as I acquire new ones.  <response>: This seems like it would be better suited for rchurning.
