Your local government would rather tax your Bitcoin at 18% than see you die with it, and get nothing. Or worse, to see you flee with it and pay another country's taxes with it. They're not going to kill you for it. The criminals will kill you for it. Protect yourself from the criminals. Privacy is only one means of protecting yourself. Be hard to attack in all ways. Be dangerous, not just hidden (be hidden too). Be physically secure, keys divided and distributed, be unassailable. Privacy is security theater. You exist, it will be known if you keep doing it.
