I think impossible. Probably ethereum will be 1.5k dollars en dof this year
1.5k dollars this year would be very good in my opinion, 15k dollars is definetely too much in my opinion...
I would be really happy with 1.5k worth for Ether before end of the year.
It is quite impossible that ethereum reaches 1 500 dollars this year. It is nearly impossible I would say. It won't happen. End of this year is too near and the market isn't in a position to act in that way. Maybe in 2019. It will be better next year.
