Eth is the one of the most underrated coin. Any it could go up any time. In couple of years it's value could be 2x of current value. It is better to invest in eth than invest in some ico i think.
Ethereum is my best choice amongst other cryptocurrency. If you buy today and decided to hold for a long time this will be profitable. Invest if we can buy and believe price will rise.
This altcoin is one of my bet in crypto currency industry, because this ethereum had a high percentage of adaptation skill. Therefore I like this altcoin because of their transparency talent, also they had a good conditon of price in the market. So I just want to hold my Ethereum because I know that maybe this year or next year their value was raising up more.
