If you have ability to hold some coin I believe that ETH will be more profitable from other. I know many alt coins are very low price now. But for me eth is better to hold a little bit. I believe you will never loss.
It kind of gives you some more security as compared to the other coins. The thing is rest of the alts are weak in long term contracts, I mean it could happen that they may loose the project development hopes, they may end up with zero investments or people leaving the project slowly and scenes like that. On the other hand we have ethereum and bitcoin which are almost the same in terms of their forever existence on the blockchain. They are non ending because mostly people choose them first and then they go for the rest. For me the most secure investment after the BTC is ETH only and then I will start looking for rest of the ICO. With current drop in the prices, yes its golden-diamond opportunity for us and must not miss it.
