Bitcoin is just about 11 year in existence, so we shouldn't expect everyone to know about it especially in a country that has limited access to the internet and low exposure to things happening around the world. Cryptocurrency is still spreading with time and more persons are still going to know about it in less than no time. Some people in the developing countries or under develp are very much with high percentage of being ignorant about it.

Many individuals still don't believe in online investment due to their past experience or news that had been flying around about how dangerous Bitcoin can be since it's has some level of privacy which can be difficult to track. With the nature of risk that are imbedded in cryptocurrency, many still see no reason of taking such adventure that could be detrimental as some level, creating discouragement and disappointment to people that might be interested in it.
