My prediction is $600 by the end of 2017, but hard to tell what it will be 5 years later.
Now this is a comment to my liking. Realistic speculation based on the current situation in cryptoland (yes the country where the dead walk among us, and I don't mean the slow moaning kind, but the zombie speed runners with fangs for teeth!). And there are a lot of balloons too, isn't this a wonderful sight, balloons and zombies!
Zombies will decompose though and balloons will deflate. But at least for now we all get to feel like Peter Pan and lick that sweet fairy dust from our hands.
5 years from now, there is no way of saying. Ether could be worth 5 dollars, just as much as it could be worth 5000
