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.
The BCH has made great strides this year. However, ETH is losing its edge to compete for influence and importance in the marketplace. But I think there are hardly any coins that can beat bitcoin. It is invincible and a prototype for the success of the crypto ecosystem.
