Bitcoin is still very illegal in many countries and to many governments, but in many of these countries, what is surprising is that you will still find investors in bitcoins who are going against the government and secretly buying and investing in bitcoins. 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? 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?
Perhaps you shouldn't have used the religious way because i don't think Bitcoin is even written anywhere in the Bible and I believe we all know that bible support anything that is good and after all we are not frauding people to get it rather through the knowledge and understanding we have and we do use our own hard earned money to trade and invest to make more money. However, I will rather go against what the government said that is wrong than to go against what God said and even some of those government are using this same asset they are prohibiting people from using.
As long as we are not doing illegal things and everything we do is aligned to the law of the land then for sure that we are fine and cannot do anything bad to other people.
But situation is different if the law doesn't allow us to buy bitcoin since this is illegal since we will commit a crime if we pursue even if the law dictates us not to do it.
So therefore do right decision which you will not have any conflict to government or anything that can put you on harm. But if the case we are allowed to invest and do things what we like then best to work clean to earn so that there would be no issue arise in future.
