I invested into AUR, but finally realised that heavy premined coin is some kind of trap.  The lesson I learned is never to trust the premined coin. The free distributed coin will be popular. C2, Faircoin prove it. Communitycoin is even better than the previous two. I believe Communitycoin will have a better market reflection.  It's my reason I want to participate.  
Also, I know I need promote this coin as a whole community will do.
