To me i think there are some part of the world that still don't know anything about Bitcoin, because there are people in USA, UK, Australia, Canada, China,etc. even in Nigeria there are people that don't know anything about Bitcoin, they always think that Bitcoin is a scam, but people that know about it are making thousand of Dollars,($) I think they don't know that we are in a digital world now.
Yeah, I agree and i think this is because enough awareness is not created although rural dwellers may find it difficult to understand bitcoin because most of them are still in the analog age and this is why i expect exchanges to help create awarenes not just for bitcoin but for the growth blockchain tech and adoption.
