I guess it´s not a Question of intelligence.

You just learn what your parents, teacher and so on told you.

And they know what they know from there parents and there teacher. It´s not really intelligence if you just keep what you´ve learnd. The Goverment, the Media and so on also don´t tell the true. But if the also learnd from other guys, they think the true is what they know. Centuries ago the truth was that the Earth was flat, because they just don´t know. Everyone who said the world wasn´t flat was an idiot. Today it´s the complet opposit.

I try to teach my family and good friends about Bitcoin. Till now they don´t believe it, which is frustrating. But i´ll go forward to safe them from the flames, because i hope they´ll just get burned a little bit and not gonna die in the flames!
