<prompt> Human: Meet John.A young lad with 100,000 cash under his mattress and a credit score of 580. His goal is to improve his credit score so he can buy a house and start a family. His bank wont give him a standard credit card so he gets a secure credit card instead. Now he has a secure credit card and the limit is 3000. John is a very simple minimalist lifestyle type of guy, so his monthly expenses are 1500 in total. That includes all rent, utilities, food, ect. So for that past few months he has been using his credit card to pay for everything. Then at the end of the month he pays the balance off in full. Three months later his credit score is now 600, John is not satisfied because he wants his score to to go up much faster. What are some options for John in this scenario?John has idea...He decided to get 3 more secure credit cards with 3000 each. After paying all monthly expenses with the first credit card, John uses the credit card from the second bank to pay in full the balance from the first card, then the third card to pay in full the balance of the second card, the he uses his cash to pay in full the balance of the third card. Would this increase the growth of his credit score by 3 times? Is this even possible? Is it a good idea, or bad idea?  <response>: You cant pay a credit card with a credit card...you could balance transfer but there are fees and waiting periods associated. Probably a lot more work than its worth.
