This idea is quite surprising. It should be taken into account that it could take care of someone's own security after death or simply lose access to their cryptocurrencies. Also, the knowledge of people about Bitcoin and some awareness would be able to become much bigger if Bitcoin existed in physical form, but does not it contradict the idea of ​​Bitcoin? Bitcoin as a non-physical form of payment from anywhere in the world when we want and to whom we want without leaving home. In my opinion, at the moment, both ideas can't work together.
