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.
That is too much to ask,theres no 500 usd price that will happen soon for ethereum as the team is still sorting ways on how to improve the platform to attract another investors
And we can see that reaction from the ICO that uss their erc20 platform in which 90-98% are failure
But expect more for the coming years as I am sure after bitcoin halving will increase the momentum of crypto market and altcoins will go along the growth of bitcoin
