Even if you're hoping for a gold-backed currency, you would be better served to purchase physical gold, because if the currency that shows up is gold-backed, you could trade your gold for currency anytime you wanted to transact, and it would be guaranteed at a specific price. But if a gold-backed currency doesn't show up, then you're protected from the inevitable collapse of that currency, with your physical gold.

I'm rooting for physical gold.
