When do you think ETH price will go up to 50usd again? 
today
Honestly i think ETH is Facebook to BTC/MySpace longer term (~2+ years). I think ETH is here to stay. I am a fan of BTC too, to be sure, and it benefits everyone for Bitcoin to continue rising and dominating in the near term. But ETH I believe will one day replace BTC in market cap and worldwide adoption. So I think ETH @ $200 in the next 12-18 months, barring any catastrophic event in crypto as a whole, is quite possible.
