I think it's important to remember that many dislike bitcoin not because of their disapproval of the technology, but as it goes against their "beliefs".
Well, most of the bitcoin haters I meet refuse to learn something new and stick to what they call "belief". I just do not understand, why people deny to be altered smarter? I mean, knowledge only makes you become stronger. impermanence is the essence of this world. Thus, accept to change make us evolve and smarter day by day
