I think when you are talking about a topic like this, I will be best to come with facts, bring clear data"s to prove your points. Do not say things based on assumptions or what you noticed from your circle of friends and generalise all Nigerians. Their are good numbers of Nigerians that are investing in Bitcoin but they don't make noise about for the sake of privacy and this is how investing should look like, which you don't need to give people impression. Please try and correct this. Bitcoin does not have any bad reputation, instead it will be better if you say our security agents misunderstand Bitcoin because people still do crime with fiat.
