<prompt> Human: I currently only have 2 credit cards. One is my oldest account that I maintain just for the age of it Its a basic Capital One account with no real bonuses and the other is the one I got when I started banking with Chase and I use it for 99.9 of all of my purchases or bills.Ive been exploring other credit cards recently Im about to move across the country from my girl friend, so Im trying to find good travel cards.I am looking at the Amazon Prime card I make a fair number of Amazon purchases and do most grocery shopping at Whole Foods... so the 5 is pretty good now, and then opening either or both?! the AMEX Platinum fee waived because Im active duty military and the Chase Sapphire next year to take advantage of the large bonus miles both cards offer.I pay my current cards off every month, so I never pay interest currently. Since my spending habits wont change with the exception of plane tickets next year... which Ive budgeted for, is there anything bad about having all these cards open? Am I going to see big hits to my credit? Im currently sitting between 800 and 820 on all soft inquires Credit Karma, USAA Credit Monitor, Chase Credit Monitor, etc and 0 hard inquires in the last 2 years.Thanks!  <response>: I have 8 cards and rotate them around depending on whatwhere Im buying. I maximize my rewards every year and I get about 500-1000 every year from my everyday necessities and wants. I dont carry a balance on any of the cards and pay them off every month. The only thing thats bad about having a lot of cards is the increased risk associated with identity theft - more cards more chances to be a victim.
