    That’s not entirely accurate. Look up Caesaceous coins. There aren’t many of them, but they do exist, and they are physical coins with a private key embedded under a hologram, which as long as the hologram has not been tampered with, is guaranteed to contain the amount of crypto it says, and you can trade that without electricity or internet.
