<prompt> Human: I am 26 years old, debt free, and work full-time making between 50k-60k a year. I know I started working on this sort of late, but I realized in January of 2014 that I had zero credit history. Neither good nor bad. I was approved for a secured credit card and started with a limit of 300. I tried to spend around 30 of that and paid it off in full and on time every month. That balance was increased to 500 over the course of last year. Yesterday I applied and was approved for an unsecured card yay! with a much higher limit. My question is, if I am completely able to pay everything off every month and continue to spend responsibly, what will be best for credit history and score? Should I keep both cards open or close the account on the previous, secured card I have? Should I keep both open and use them every month if I pay in full each time? Thanks in advance for any input.TLDR: New, better credit card. Should I keep both open or close the old card?  <response>: You put a deposit on the secured card right? If so, close it to get your deposit back. Pay your statement balance in full each month due date. Dont obsess over your credit score. Your credit will get better over time as you make good choices.
