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 would be a great price to end this year, even if it's gonna go with its current rate, I think that's gonna happen provided BTC will double its current price. When BTC rises, ETH's value will also affected, maybe some dump as part of the normal reaction but in overall it will help to increase the value of ETH. BTC doubling its current price means it will create a new ATH, and with that, it's also possible that altcoins will finally wake up and ETH will surely lead the way.
