It's easy to say it here in the Bitcointalk. There is always at least one point which can be used to support such statement. But let's go and ask people in your city or just family. Who is using Bitcoin? There is a long journey for Bitcoin to be global currency.
I think that Bitcoin need more support and advertising as you noticed here, there is a lot of people ouit this forum not knowing anything about this powerful crypto currency
So yes, i think there is a remaining long run for bitcoin to become global as we wish
