if you want to avoid taxes at all, just pay in bitcoin directly, and never exchange them, even if they track you, they can't do shit, because bitcoin it self isn't taxable, is just the gain in fiat that it is
This is very bad advice that can get you in trouble if you follow it.
how so? something like this could only help adoption(as long as everyone will do it, merchants too), because it prevent dumping btc for fiat
