Not even Vitalik will make this kind of call. It is simply outrageous but then, this is cryptocurrency, the most volatile market and anything is possible. My best call is $600 before year end
This year, yes. $600 might be the best price. Further, if something changes greatly, and Bitcoin starts gaining, Ethereum can jump. I believe it will reach 2,5 K, but in several years.
yes, for sure eth will not touch $2500 in this year, and maybe the best price of ethereum in this year is between $500 - $600 not more
