Etheruem is a top coin in crypto currency, after bitcoin the next alternative is etheruem that's why it plays a major role in the faith of other altcoins in crypto currency because most altcoins are built on the platform of etheruem which means any factor that affect etheruem will affect most of the altcoins. Etheruem decline in price that's why most altcoins drop massively in price, but I pray it will recover very soon than we thought so as other altcoins.
