Bitcoin has always had scams, hacks, etc. This is not something new, and it is not a fault of the currency. The reason why there are so many scams in bitcoin is that people do not do their due diligence when using a service, especially people who use dark net sites.
But this is a contributing reason for the negative media and publicity surrounding Bitcoin that has somewhat stalled new users (some people are just scared off and too ignorant to look into it or just have no heard of Bitcoin at all). There isn't really anyone selling the positive points of Bitcoin - most media outlets just affiliate it with cybercriminals and buying illict drugs.
To an extent, I can understand where the OP is coming from - Bitcoin has yet to reach the mainstream adoption it requires to be truly successful. As to whether it will eventually happen one day - that is yet to be seen.
