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.
Knowing nothing about Bitcoin and knowing something about Bitcoin can lead to a same decision, don't invest money in Bitcoin.
Knowing something about Bitcoin from media, educational resources can be good starts for a debut of investment in Bitcoin but it does not guarantee that these people will surely do investment.
Have knowledge about Bitocoin and have investment don't mean they will be rich with Bitcoin. Only people with good investment strategy and good capital management, will get profit with Bitcoin.
