guslSuppose you buy some stuff with credit card A.
Then you pay the balance on card A (due on the 30th of the month) with card B (due on the 15th)...
and then you pay off card B with card A.
and so on...
(You never use card A or card B for anything else)
Since you are never late, you are never charged interest. If you never miss a payment, will this balance just float around forever? And besides, aren't you accumulating advantages every month? (dividends, airmiles, whatever)
