on Ethereum, i don't think the coin is coming back anytime soon as it faces further decreases in the price, as at today the price is 187USD, this coin has been struggling to climb up to it's formal state, i still hope the price hits 500USD or more by the end of the year.
i think it has nothing to do with the differences between the price. ethereum is still being upscaled by vitaik and his team and there is no doubt that he will deliver on his promises of scalability. the recent update on the ethereum website has shown that the further advancement of the platform will also give an increase in the price.
