<prompt> Human: So Ive got the Chase Sapphire Preferred which I love, which gets 1 mile per dollar which is about 1.25 miles back. But there are credit cards out there that earn 2 cash back as a statement credit. Which makes me think, shouldnt I choose that, since I get, like, nearly 2x back versus miles? And its basically cash equivalent instead of miles?I get how miles can be useful when redeemed and I can get nice perks like double back on dining and stuff, but doesnt it make more sense to get cash back instead?  <response>: Miles, in some cases, can be redeemed for more than 1 cent per point, sometimes much more. To take a simple example, Citi ThankYou points are worth at least 1.6 cents per point if you have a Citi Prestige and redeem on American. You get 3 points back on travel, 2 points on dining, so thats 4.8 and 3.2, much better than 2.There are also signup bonuses on many pointsmiles cards that can be significantly valuable. Taking that same Citi Prestige example, the signup bonus is 50,000 points after 3k spend, worth at least 800 Im ignoring other perks and the annual fee for the moment, but those are also considerations. Most cash back cards have no or little signup bonus.rchurning is dedicated to getting this kind of value out of credit cards
