Ethereum won't migrate fully to PoS untill 2019 earliest. EOS will be launched in 3 months at 10k tps single threaded, DPoS consensus. Any backing right now doesn't mean much, its all a bubble, its really anyone's game. The tech, the innovation, and most importantly the END USER EXPERIENCE will win in the end.
