I find the biggest problem about bitcoin being illegal in a country that one should not buy/sell bitcoin. If he does, he can get into trouble, no matter what OP tells.
However, there are ways to earn bitcoin if one has the skills and the patience. And this can be just enough. Sooner or later bitcoin will be unbanned and one can find himself quite a HODLer at that point. Of course, it needs trust and patience at super high levels.
