The future for Ethereum looks good, but Bitcoin's looks better. I personally buy Ether all the time but get out of it quickly. I mainly use it to increase my bitcoins, and that probably goes for a lot of people. Bitcoin's popularity is soaring right now, Ether - not so much, so would you rather own Ether or Bitcoin? That's the only question you need to ask yourself. Keep in mind exchanges are starting to kick low volume altcoins which will pretty much seal their fate, but as long as the volume of Ether stays high it should still be fine to own it. Just be warned there is a TON of ETHER, it's new, and there is a ton of whales ready to unload at a moments notice thus crashing the price. Plus the average person getting into bitcoin won't even glance at Ether nor would careless about it. That may change in the future though. Who knows.
