In my opinion, yes. ETH has proven to be pretty resilient as a coin and I strongly believe in its long-term well-being. Thanks to the ERC20, this makes the altcoin even more valuable and less imitable. Therefore, yes, ETH will rise substantially in the long-run. I've spent a fortune on it, on Ada, and IOTA. Among the ICO's, on the other hand, I'm very fond of Knowledge, Giftz, and Dadi.
