...so I am want to ask a personal question, do you think of yourself as a bad citizen for disobeying the government? 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?
It really depends on the law; its universally accepted that stealing is bad, Bitcoin is legal in one country and illegal in another so its not universally accepted that holding Bitcoin is bad; its just the government that makes it look that way.
I don't think you are committing a sin, but you are violating a law in your government that makes it bad for their citizens, so its on your discrepancy if you think that you are violating then don't hold if you believe on Bitcoin and you think you have future holding it, then go hold, just get caught holding, its for everyone's preferences there is no one rule.
