Please advise us what currency is NOT a scam.
I'd think the only kind that isn't a scam is the kind created by God - Gold and Silver. The metals have tangible, real value (usable in manufacturing, jewelry, etc.), and they cannot be destroyed. No wonder governments give us valueless paper instead (or worse, plastic, and now even worse, phantom 'internet money'). Everyone has their opinions on gold, and these are mine - go back to the Gold Standard (but that'll never happen with a chip environment immanent). No one actually uses money anymore. It's been basically removed from society while the masses use plastic for 'value' shopping.
Check out Mark Dice (he has a few on this topic, picked this at one random). The man can't even give away gold these days because almost no one has any clue on its value. Wow.
