Not surprised this guy wants in he is the epitome of scummy money imo. I hope this endeavor fails spectacularly, I don't like the Uber inventor. This also won't be the last existing company to try and enter this space, earlier today I heard about Mercedes Benz wanting in too and they are going to have their own called "MobiCoin".
Its interesting to know why you dont like the uber inventor? Do you know him personally?
However, i will always support if company which already have working product want to start their own cryptocurrency that can prove cryptocurrency become more popular.
