It will breack $10000 by the end of this year if bitcoin does not crash hard. Also there is a news saying that vitalik return to focus building next update with proof of stake. And for me. Proof of stake is more reliable for scaling. It is not using alot of power to mine. At mid 2018 ethereum probably will break $4000 mark and then correction again.
Absolutely there's a possibility that ethereum reach the $10,000 in the future but I guess it takes a lot of time before it happens. I know its hard to believe that but in my sight after this crisis coming in crypto currency community it will recovered and back in to the growing up stage. No doubt with that because for the past year we can see the fast evolution of crypto currency in digital world.
