If you follow the uptrend from Ethereum chart 📈 from January 2017 till now, you will see that ethereum as done nothing less than x110 of its current value as at 1st February 2017.
However, should ethereum repeat this feet in 2018 then it will be $132000/eth in twenty 2019.
Calculation:
1st February, 2017
Ethereum Price/$
1ETH = $11
10th January, 2018
Ethereum Price/$
1ETH = $1200
$1200/$11 = x109.091
If continue this uptrend in 2018 of which as started already and return another x109.091 by January, 2019. Price/ETH will be $132000/ETH.
I think if happened last year, it can happen this year, buy at least 1 ethereum and hold.

That are some cool facts and i think that they are able to make me believe that this coin could reach that level in even shortert time than you wrote.
