Bitcoin is still very illegal in many countries and to many governments ~~~
How do you define "very illegal"? 
Sure, the legality of Bitcoin depends on the laws in the countries, it can be legal or illegal.
I see nothing wrong with this, we only follow the regulation in our respective countries. Here, it is legal for investment, so we have no problem to invest in Bitcoin. Meanwhile in other countries that it is still illegal (both for investment and payment tool), kindly avoid utilizing Bitcoin because you may get a problem for holding Bitcoin. Just be patient, I assume it should be legal everywhere in the future.
~~~ 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?
Dude, when you buy Bitcoin, you don' need to get a permission from your government. It is a decentralized asset, there is nothing to do with your government. As long as the regulation in your countries allow Bitcoin investment, it is always okay to buy Bitcoin any time without a permission from your government. You only brake the rules/regulation in your country if it is not allowed in your countries.By the way, in many countries, we pay for taxes for Bitcoin investment. Even in our local exchanges, we pay for taxes in each transaction in the local exchanges. So, nothing wrong with this, we even give the contribution for the income of our country.
