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.
Honestly, many are aware, but few truly care. Ultimately, Bitcoin won't emerge as a mainstream currency; instead, countries will likely embrace their own digital currencies. Bitcoin is simply another asset for speculation. With the introduction of ETFs, it's essentially morphed into just another tradable stock.
