if I understand correctly everything, after implantation of the implant, a person can pay with a fingerprint and an iris of the eyes, if they can take me hostage and take my prints, then I lose all my money? Is not it better to keep money in a safe place than in the body?
Your missing the big picture. If you dont advertise you have Achilles no one will ever know you have it. Stored in your body under the skin. Paper money is physical. People can see it touch it. So if someone sees it they can try and steal it. No one can see achilles . If you keep your mouth shut you could be walking around with $100,000,000 in your hand but no one would ever know it. Hostage situation is far fetched if you dont run your mouth about how much money you have.
believe me, when a person has 100 million dollars, someone knows about it, just not who no can take off his savings because these people do not keep everything in one place
