Bitcoin is still ethereal and mysterious to many people. Many people get their news from the press, hearing the talks about the illegal activities and the rise and crash of the price. If any acceptance is to happen it will have to be after a renewal of information.
That's true bad news travel faster then good news. People are just looking at the news that media is providing them and they just start to believe it without any research or investing their knowledge in it and Government is supporting media to do so as Govt is also against the bitcoin.
Too much people link btc to dark martek. This is the worst advertising you can do to btc. Govts hate to lose thiers controll to people
