We actualy dont know what will gonna happen in the future but i think that price is way too far lol! In my expectation maybe etherium price can reach that high the future maybe 10 years from nowbut thats not guarantee that the price can be that high.
I agree with you, that number is too far if use this year's parameters. it still takes time for the etherum to touch that number. although the market is sluggish but at least there will be an increase at the end of the year 2018, hopefully I'm not wrong
