I guess that will never be happen. Although Bitcoin price was dropped up to $11,000.00 USD from $17,000.00 USD it is still so hard that ethereum will pass this amount because ethereum also dropped
$961.91 USD and that is very far to beat the dropping value of $11,000.00 USD of bitcoin and how much more when bitcoin rises.
But until now ethereum coin are still doing their best to reach even a little bit part of position of bitcoin in crypto currency community. I think this 2018 ethereum coin are largely increase their value because on the first month of the year it will started to grow up and all I know it was not broken down again but I was wrong. I forget that increasing and decreasing fluctuation of coins are normally happen. However I still believe that ethereum and other altcoins are raised up regularly, maybe not now but in the future.
