I've been studying every damn article about bitcoin for the past 9 months and focusing on a macroeconomic level, $6000-$10000 is definitely realistic by the end of this year. If nothing else, just think about the ridiculous amount of infrastructure that currently being built for it AROUND THE GLOBE... its happening whether anyone likes it or not. (unless something completely drastic happens which no one can predict including me...)
With that said, I'm in the process of putting together a project to help facilitate mass adoption of Bitcoin. Let's hope I have something to show the community soon.
