ETH seems like it has some potential, but I have a feeling it is going to end up being a massive bubble and eventually collapse. There are so few things that are actually viable on it, and it seems like there is a massive lack of a user base actually interested in supporting it rather than just investing in it and then selling it all off.
It most likely WILL be a bubble. As soon as it reaches a high enough price, the investors will start dumping. I don't think that it has as much of a community backing as Bitcoin, which still has potential. The good thing about Ethereum is that it's allowed even more support to come to the cryptocurrency scene, and it could attract investors to both Ethereum and Bitcoin.
