However, the ONLY thing that has passed the test of times as real money, is the only real money we've ever had, and that is PMs. Gold for wealth preservation, and silver for more practical uses.
Well, you could tokenize gold on the ethereum blockchain and digitize it that way (and it's been done I presume, probably several times over). But that just begs the question of why worry about trusting whether a token is really backed by gold in a vault somewhere?
I suppose the >60 generation of goldbugs will never concede, but they will die off soon enough. Very, very few younger people have an interest in PMs. (I held gold when I was younger, and it was literally the worst investment I ever held). Interest is all shifting towards cryptocurrency. PM's only have an edge over crypto in an apocalyptic scenario.
