For me Ethereum is the best coin that now exists. Great support for people, as well as an experienced team of developers know their business. My forecast is as follows: 6 months - 2000-3000 $; 1 year - 20,000$.
Very optimistic assumptions but it is unlikely that eth can do it. I think that reaching 2000 $ will last much longer than six months. And 20k $ a year is definitely not an option.
