Reason I'm asking is I think I might get my head frozen after all when I die. Tattoo "I have bitcoins", include a couple of Trezors in my mouth with a good PIN, and in a thousand years when Bitcoin is worth infinite amounts it would be a reasonable reward to dethaw my brain and put me on a top of line body.
Hm....
that is the future! everyone dying will put a btc address on his grave stone and pretend to have the keys "in his brain". future grave robbers will have fun trying to figure out who was genuine.
also: imagine the plebs trying this with IOTA. or Bcash/BSV
