Most times it's just better you maintain some privacy because it hard to trust people these days besides most people here in Nigeria are brainwashed that all people that are into cryptocurrency especially Bitcoin are fraudsters, they know little of the world of bitcoin so they can say shit about it and you announcing yourself as a Bitcoiner can make the situation worse.. they aren't gonna believe you but try changing your mode of dressing too
And again you actually owe no one any explanation about what you do and besides if we really look into the whole thing at hand I think staying private would actually benefit you more than actually letting people know that you are into Bitcoin cause just like you said the whole society is brainwashed to the mentality that Bitcoin has to do with scam@yahoo boys .
