I was only talking about the account name/id that one communicates and sends safecoin via. When you get to the physical exchange, that’s another matter. But even if identified with that account for that exchange, you can have a new one any time, so it’s “just” the tracking of the body that needs to be solved. On this point, the book “Thieves Emporium”, by Max Hernandes has some insights.
Made this post about the book last year. https://forum.autonomi.community/t/thieves-emporium/1709?u=fergish
