how would IRS know what you mined?
For those of us who don't want to pay an insane amount of back taxes, maybe lose our home, or worse, end up in jail, let's pretend for the sake of argument that they do know how much you mined. Most miners are eventually going to change their bit coins to USD, and in that case, it will be very hard to cover up.
What I really don't understand is that no one seems to be talking about it on this forum.
