Yes, i think that ETh will be best coin in 2018 But price can not go up 5k$ Because a lot of new coins also potential. In My opinion, the end of 2018, ETH of price is 3k$
The value of the Ethereum at this moment is magnificent, for all those who could not previously buy it, this would be the moment
try as much as possible to keep it several months and so be able to see how your portfolio begins to grow. And this would make nothing is
impossible and reach that value for the next few years.
