Sane should be 1$ in the near future (2 or 3 months), if bitcoin stays in the 6k-7k range.
Possible in the near future are like 3$ I think, maximum (insane).
In the long run (1 or 2 years) I see it hitting atleast 10$, but that also depends a lot on bitcoin
Staking rewards will be reduced from 20x42 to 5x42 around next november, thats when I expect the price to start going crazy.

A bullrun combined with the reduction of the rewards and the release of the Dapp store, reputation system etc might make it skyrocket, so I'd say 50$ are possible as well in around 1 to 2 years ( a bit insane, but I think it will happen with that team)
