<prompt> Human: I know paying a credit card off with another credit card is generally a sign of painful overspending and what not.. but Im looking at all these points cards out there. Whats stopping me from spending 1,000 on Card A and get 1000 miles, pay it off with Card B and getting 1000 points, pay that off with Card C and get 100 Cash back and then just paying off Card C out of my checking?  <response>: Most credit cards dont let you pay with a different credit card, and balance transfers typically dont give rewards.
