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.
Because the altcoins season hasn't happened yet and once again we see that prices are coming back down now, 500USD at the end of the year seems to be possible for ethereum but if this trend continues then I think to survive at 200USD will also be very difficult because prices continuously corrected on an ongoing basis.
