I believe the price of ethereum in the future will increase more maybe the price will reach that price after few months. But this year the percentage to happen that price is low because the price of ethereum is stable and slow increasing but for sure the price of 1000 dollars is possible to happen in the year of 2018. You can buy more ethereum and those peole have ethereum is better to hold it.
Yes I agree with you price ethereum in tahun2018 will be more 1000 $ because according to my prediction ethereum sold more than 1000 $ .to ITI have ethereum hold the first to sell next year.
