Ripple has been sucking KYC information for the US government and for Banks since it's release and any true Crypto currency enthusiast will tell you that it is a bad idea to gamble with coins that are 100% traceable.
They did a poll.
They didn't hand pick Ripple. People wanted it, Stake.com delivered. However, I am not sure if these polls were completely honest. People can create multiple accounts to vote and Ripple bois are famous for the massive amounts of bot-like shilling on twitter and reddit, so...
I believe CMC has the biggest role in this bullshit. Whatever credibility/fame Ripple has now they owe it to CMC. If these noobs didn't list that PoS in the first place Ripple wouldn't even exist now.
