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.
It will be very difficult to have Altcoin that can touch the price of the BTC. Because BTC is the mother coin, it governs the price of all altcoin and crypto market price controls.
Although there are a lot of good tech coin present, it is only a scramble for 2nd place. And once again I assert that overcoming BTC is impossible.
