Our Government here will always question people who become rich instantly, sometimes they will relate all the wealth to drugs and smuggling so they can send us to jail for a questionable wealth and not paying taxes. they will do background checking, even if they dont find any illegal activities we did they still think that we do illegal. What if I become rich because of BTC do you think they will believe if I say that its bitcoin that making me rich? How will I explained to them?
Their are questionable wealth because of cryptocurriencies because your going to be rich instantly but they don't know that you are gaining the money because of your knowledge and efforts every day
