from what i understood in the article is that they are afraid of bitcoin being used in the wrong way, as bitcoin provides total anonymity to the person usi,g and banks and goverments will not be able to track down the money entering or leaving the country or wether it is legit or not, many countries are having the same prespective but some of them are afraid of it so they ban it, like  maroco and indonisia and russia to name a few, and others relized that they are unable to stop it so they embrace it and try to use it for their advantages.
