People often throw a bad judgment on Bitcoin. They say "Bitcoin is only used as money for illicit drugs, prostitution and other bad behaviors". they generally condemn the currency as a channel for activity in order to undermine its credibility.

However, this attempt to punish Bitcoin and its user base is intellectually dishonest and distances it from utility, utility and luxury. They stopped all the wholesale market economic activities going on as well as the good things about the black market. But much worse, they look like using Bitcoin for inherently unscrupulous undercover activities.

For example, in August 2016, there was an article that says that Bitcoin has just been used as a way to perform actions that look creepy;

In the article it was mentioned that someone had interviewed six speakers from the black market. The resource persons use Bitcoin to buy drugs, sell sex, avoid regulations, supermarket account exploits, gambling in Las Vegas and much more.

Indeed there is really no problem with the various activities in the black market. It's all an individual choice. Anyone who tries to control a person's drive to have drugs or sex is a tyrant trying to subdue another person. It is not high morals to harm someone if they just pursue their own version of happiness. This is called individual sovereignty and this is important.
