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,
When you say someone did not know anything about something, it simply means they haven't heard anything related to what you are talking about before in their lives, but if they have heard about it before, even if it's negative, they definitely lack knowledge and won't be blamed for such an act. So the best thing for people like this is to let them be aware of the positive sides of bitcoin since they believe it is a scam. Perhaps it is due to past experience that you let them learn how they can make money from bitcoin.
but people that know about it are making thousands of Dollars,($) I think they don't know that we are in a digital world now.
Of course, they will do it because they already know everything about it and believe and are also willing to take the risk. However, the world is now doing things digitally, which makes things easier for us.
