People coveniently tend to forget that the few tens of thousands who buy their drugs through various online dark markets represents only a small fraction of the millions of drug users world wide. Right now, less than 1% of the drug users buy their drugs online. But as the CIA and the FBI churn out more and more negative propaganda against the Bitcoin, more of these people will become aware of dark markets and will consider buying their drugs from there.
Yup. As time goes on more and more people will flock to dakrnet markets as they'll get more popular and even safer. With movies and documentaries and plenty of mainstream media mentions it's only serving as free advertising. People clearly want their drugs and they're going to get them any way they can and for most darknet markets are the safest and easiest ways to facilitate this.
