It's almost 8 months of 2018 and we have not seen any reasonable hikes for the altcoins,
It was only Ethereum that hit a good value of almost 1.4k$ in the beginning of the year . Since then it's pretty dull.
Forget overtaking can any ALTCOIN ever reach a value near Bitcoin.
In my opinion, it cannot really happen, bitcoin is way to high compare to altcoins or even to the top 2 cryptocurrency in the world. Bitcoin will still prevail no matter how good a project is. Do you guys know what good is in bitcoin? its name.
