When Ethereum came out, it was looked down upon because the market hadnt matured yet. No one understood much about cryptos beyond the peer to peer transfer. When the difference between Bitcoin and Ethereum was established, that is when we had a surge of the altcoin rush. This caused prices to skyrocket on all altcoins. It seems as if the roles have been reversed and there is more doubt on Bitcoin than anything else. This is why we recommend you hodl Ethereum over Bitcoin.

So it would be right to go for investing in Ethereum in 2018 and apart from Ethereum you can also go for other altcoins like Neocoin, Ripple, Railblocks, Siacoin, Bitshare where these coins are having high potential to give you good returns in the coming year. Myself personally invested in Neocoin and Railblocks for this year 2018 for long-term gains.
