This is what I think: Ethereum will survive and Ripple will die for sure. Why? Because Ripple is centralized. Just my opinion, though

I agree with you. In any case, the ethereum must survive, but the ripple must probably die.
I hope that ripply not gonna die as I invested in it and believes in it in such a way as I believe in bitcoin and some altcoins, but let us see some updates in the coming days or months if what would be the fate of Ripple, hope it will still grow.
