If indeed the country has been legalized bitcoin, it's good we aimed the all efforts made only focused on the things that are legal. Anyhow I don't think bitcoin is worth using for the things that smelled illegal. To me personally in the country where I live, although bitcoin is still said not legal completely.. but I personally keep doing things more positively and avoiding things that smelled negatively, criminalized, or illegal activities like for example made into a dark business.
There are people who are using bitcoin for legal stuff but it doesn't change the core issue that bitcoin is in the hands who prefer illegal activities. The dark market which is tor supported which is solely financed through bitcoin. The same is used for more dangerous activities than drugs and arms dealing. Bitcoin is facilitating psychopathic groups which humiliated humanity. Payments are received in bitcoin to watch live abuse and murders. This is the scariest aspect of bitcoin.
