If I'm not wrong OP should change the way he introduce bitcoin to new people. Atleast prior to introduction we should understand what kind of people we're talking with. Not everyone have the mind to accept it, when they've got good sum of fiat. Maybe thats the reason why uncle keeps saying something against bitcoin. It is always necessary to make some connect with the public regarding bitcoin. One should not expose that he's bitcoiner. We should simply introduce about the existence or while discussion happens relative to technology.
