Ethereum is related to Crypto world more than Ripple can ever be, I love Ripple and I have money in it but the truth is Ripple should not consider being Crypto in the first place, yes Ethereum is all about ICO but guess what! ICO huge thing in Crypto right now even with the recent decline in ICO's, ICO's remain one of the main things in Crypto space, in other words, Ethereum is responsible for the appearing of a lot of successful projects we have right now including projects that are trying to compete with ETHereum like EOS and TRON they started buy running an ICO threw Ethereum network.
Mark my words Ethereum will regain second place very soon, sooner than some might think.
