In my research, many countries know about bitcoin, but many do not believe in bitcoins, because most know about bitcoin scams, scams because they do not know how to do it or process it, they believe they are different man legit it. But those who know bitcoin are the only ones they talk to their friends or family.
You can't blame them because there's a lot of scammers took advantage of crypto to exploit and took the money of unsuspecting victims that why countries decided to put a outright ban on crypto specially ICO's. And also media portray crypto in a negative way. But for bitcoin, its really unstoppable at this is the only coins that people are going to adopt and embrace in the next coming years.
Some people are double minded because some say that bitcoin is a scam and just a waste of time and some day that the future is that of cryptocurrency and it will take over the market soon. Gradually all the people in the world will come to know by local means and then they will tell others about cryptocurrency and bitcoin. I tell people the features of cryptocurrency.
