<prompt> Human: Hi Redditors, Ive been thinking about getting a credit card lately to build up my credit and get some rewards. Im looking at the citi double cash back card 1 now 1 when you pay. Im 25, make 52kyear, have a good credit score but not a very long credit history, have no debt, monthly expenses are 500, I have an emergency fund setup, currently maxing my 401k and contributing to a Roth IRA, and have 30k in savings.Im looking for a credit card with no annual fee and some sort of reward. I have researched the no annual fee cards on nerdwallet.com and think the flat rate rewards card is appealing since I dont want to fumble around with rotating categorys every quarter or have a discover card that isnt as widely accepted. I plan to buy everything on it instead of using cashdebit card and paying it off every month. Is there anything Im overlooking or should consider? I appreciate the advice.  <response>: I have the Citi Double Cash. Big Fan.
