I have the opposite view of you, we should not let government be a barrier to our future. I know breaking the law and violating the state's regulations is not advisable because it is very risky. But bitcoin is not something as harmful as drugs or terrorism, they ban it just because they fear it, not because it endangers people. I am a law-abiding person, but in this case, I will not listen to them.
The government won't be responsible for our future, so we shouldn't do everything they say, we should choose what's best for us. OP's government bans bitcoin, but it doesn't mean they will ban it forever, so as long as OP is quietly investing, nothing serious will happen.
Regardless of what your explanation regarding how good bitcoin is and how good the technology behind it, it doesn't change the fact that it's too risky, of having it on a non-bitcoin friendly country. It's always easier said than done. I awe how brave OP is but just like said, always do it in very cautious and secured way to not get detected of the authorities.
I'm not saying that investing in bitcoin in a banned country is without risk, but there is always a way to get around it, and that's not a big deal, IMO. When I first started investing in bitcoin, my country also banned bitcoin, and I never had a problem during that time. Now they lifted the ban after many years of embargo, and if I had followed them, I wouldn't be where I am today.
As I said, bitcoin is not a dangerous thing like drugs or terrorism, their ban is temporary, and we can keep investing in silence until they change the ban.
