This case depends on the decision of a country, if they (government) consider everything about bitcoin is something that is illegal then inevitably bitcoin users in the country must accept the consequences. Bitcoin is indeed freely owned by everyone, but users should be aware of where they live, there is a government that will manage all the life of a person.
In fact, there are some countries that prohibit the use of bitcoin only as a payment system. Some countries allow bitcoin users to trade with their records (the government) does not have the authority to manage and be responsible for any risks to be faced.
