Predicting the future is pointless but can be a fun discussion. I don't have any grand opinion - I foresee the usual obstacles: 1) Slow adoptions, 2) Challenged perception issues from the uninformed, 3) Potentially some dilution by competing crypto currencies.

I have stronger opinions on what needs to be done to help Bitcoin. Bitcoin needs to become more familiar with a greater part of the population. Not that the population needs to use it but the population needs to be more aware of it, to the point that it's not a mystery or clouded by misconception. This can be done easiest by mainstream businesses accepting bitcoin for payment, having the "Bitcoin accepted here!" signs next to registers. Adoption by the broad population doesn't need misconceptions to be explained, they just need to see their neighborhood and nationwide stores use it...most people won't even be curious enough to care about the misconceptions at that point. They'll see - Carrefour accepts it? It must be good!
