So, you're willing to bet on the assumption that the government will want your revenue, not your coins? If they see you earning 500k a year from Bitcoin they might want to knock on your door and see what it is that you're doing exactly. They can take your computers for examination and we all know how hard it is to get anything back from the police, especially if those things are valuable. Usually when it comes back half of it is missing and nobody can find out who and when had access to it.
