It's funny you mention that.  Out of the large section of people I know from bitcoin, this is how it breaks down:

IQ 80 or lower:  Thinks bitcoin is some type of pyramid scam or poorly designed centralized garbage that will implode

IQ 95-105:        Thinks bitcoin is the greatest invention since the wheel and will be the world reserve currency

IQ 110-140:      Thinks bitcoin is some type of pyramid scam or poorly designed centralized garbage that will implode
