It's true that our friends speak bitcoin without learning it first, they just talk, after I explain about bitcoin, they accept it and many want to learn in the forum.
Many people hear about cryptocurrency, but not everyone understands what it is. Everyone has a different reaction, but when they hear about how much they could earn, they start to get interested.
if they know how much our earning from this world, maybe they will interested and trying to join on it too.but usually first reaction did not believed about crypto and considered it as ponzy.
