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.
It's true that there are still many people around the world who are not familiar with Bitcoin and may have misconceptions about it being a scam. Bitcoin and other cryptocurrencies have gained popularity in some regions, but there is still a lack of awareness in many parts of the world.
Conclusively, for me think I it's lack of awareness, just like I stated earlier
