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.
Every country in the world knows more or less about Bitcoin. But show me a country where all the people of that country know about Bitcoin, I don't think there is any such country. The name Bitcoin is probably known by the governments of all countries, more or less by the people of all countries. Currently people between 10 years to 45 years are familiar with modern technology, most of them are using Bitcoin and know about Bitcoin. I live in an underdeveloped South Asian country where most of the people don't know about Bitcoin, even a third of the people in the country have never even heard of Bitcoin. The digital world is advancing, people are now showing interest in digital coins. Soon Bitcoin will become widespread.That is, there are people in the world who do not even know about the Internet. They have not even heard the name of the internet, let alone how the internet works or why to use it. Actually, they don't need it so they don't know. Do not talk about them here.
I think every country in the world is now aware of Bitcoin. Because you know most of the countries still have restrictions on Bitcoin usage either directly or indirectly. If they didn't know about Bitcoin, they wouldn't have banned it. But I strongly believe that a time will soon come when paper money will disappear and people will start using e-currency. And globally Bitcoin will lead all e-currencies. You may argue that this is never possible, paper money is needed. But time will tell everything. There was also a debate about whether man went to the moon.
