<prompt> Human: With so many 14-18 month 0 APR promos, and the fact there is no limit to how many credit cards you can own, couldnt you theoretically apply for several new credit cards with the same 0 promo every 12-14 months or so, while only paying the minimum payment each month and not going over 30 utilization overall hence, credit score keeps going up, indefinitely? If you have a high enough total credit limit then 30 is a lot of money. Is this something people already do? Am I missing something?  <response>: Missing the day a new 0 Card does not approve you.
