Scams are not only related to btc, they're everywhere in life, but btc is not regulated so he will be usual suspect..
well yeah, many people hate bitcoins because they believe it gives great possibilities to commit crimes or buy illegal stuff with it as bitcoin is anonymous though thats a bad position
i think that people shouldnt hate it just because of crimes that are being done with it because it is possible to do the same things with fiat too, also people should love bitcoins because of possible price growths
