So, you think Ethereum with it's centralized authority and Ripple will take Bitcoin down? Bitcoin has no single authority and no founders who got pre-mined coins to line their pockets with free money. Ripple is a Bank coin and no true Crypto enthusiast or investor with some crypto currency knowledge, would invest in that centralized technology.

Only the fiat slaves will go for a technology with centralized control and authority, because they want Crypto currencies, based on that financial model. ^lol^
