 They donate a portion of every purchase you make to conservative causes. So you can stay with some left-wing credit card company that's trying to fund nonprofits and things that are really hurting the country, or you can make sure that you are using a great credit card that gives you really cool cash back, for example, 1% cash back on every purchase you make, and donates a portion of every purchase to conservative causes. That's where Coin comes in.
