<prompt> Human: I have a hypothetical question, that obviously should not be done in real life due to interest, but would a credit card loop possible and would you be able to manage it enough to the point where you could continuously pay your credit card payments with other credit cards without your credit score taking a hit, for the rest of your life? Example: I apply for 20 credit cards over a period of time and get accepted with all of them. Each credit card has a 30,000 credit limit. I buy a TV for 6000 with one credit card A, and get a bill next month. I pay the 30 bill with credit card B by taking cash out of an ATM and sending cash in. Next month a credit card bill comes from A and B I pay credit card A with credit card B and pay credit card B with A... I continue on until interest starts to cause card A starts going past 25 of the credit limit due to interest, and then start using credit card C to pay off A and use B to pay off C... continue on and on and on for the rest of my life carrying the 6000 purchase plus interest across several credit cards. Is this theoretically possible to accomplish while maintaining a good credit score and basically never pay for the item you purchased? If so could this be applied on a bigger scale? Lets say you are rich and have a credit line of 1,000,000 on each card and buy a 750,000 house in cash. Are there any protections against people doing this?  <response>: You cant pay for a credit card with a credit card.If you take a cash advance off card B, you are charged an additional premium on your standard interest rate. If you tried to do all this the lending institutions would win and you would lose. Youre not going to best them except by paying what you contractually agreed to pay when you took the card. Ps.the credit bureau has a score which begin to tank and lenders would stop granting you new ones of credit.
