Anyone can suffer addiction. It's actually fairly common. Whether it be serious things like alcohol, gambling, drugs, or even more mundane things. Some people spend more time than would be considered healthy on social media, for example. It can still be considered an addiction. Most people just develop coping mechanisms so it doesn't have too much of a negative impact on their day-to-day lives.
Again, see my post here where I highlighted some trading behaviour that sounded incredibly unhealthy. If you're not eating or cleaning because you're glued to a screen watching trades, that's not normal.
What I see with the UK hospital's rehabilitation program is a form of promotion for their Business. This way health industry too is making money in the name of bitcoin.
