An example of some of these people are members in this forum, so I am want to ask a personal question, do you think of yourself as a bad citizen for disobeying the government?
Bad citizens are people who engage in activities that harm and could negatively affect the reputation or the economy of a country. I don't think Bitcoin is causing any harm to the country, so I will not be termed a bad citizen because I own it. Even the people who make the law disobey the law and the ban on Bitcoin was made because of the selfish interest of a few influential people.
Do you agree that you are a violator for breaking the law? Now see things from a religious side as well, by disobeying the government and investing in bitcoins, are you committing the sin of direct disobedience?
Legally I am breaking the law but morally I am not. These politicians don't have any genuine reasons for banning Bitcoin. The reason for this ban is purely for personal gains and not for the good of the people.
Religiously, I am not committing any sin because my religion doesn't forbid investing in Bitcoin or using it as a legal tender. My religion promotes freedom and privacy so the ban on Bitcoin is even against my religious tenets.
Citizens are mandated to obey the law of the nation they are staying in. If Bitcoin is banned in your country, you are obliged not to buy or engage in any Bitcoin transaction.
But you have the option of travelling to a neighbouring country where Bitcoin is legal to engage in Bitcoin transactions and move back to your country. If you take this step you didn't disobey any law since you didn't engage in the activity within the territory of a banned territory.
