Make sure to check out this interview with Trace Mayer and John Rubino regarding digital gold currencies and the collapse in the value of the dollar.
John Rubino co-authored "The Collapse of the Dollar" with James Turk.
James Turk is the co-founder of GoldMoney.com (link). An organization located on the Jersey Islands that stores silver, gold and platinum for clients in Zurich or London. It's a digital currency system that can be used to settle transaction and trade metal. It's pretty slick. You can sell your metal into any currency you wish, swap metal for metal and swap currency for currency.
And in a jam, you could hop on a speed boat, go to Panama, open a bank account and wire funds to yourself from your GoldMoney account. If you don't understand why you'd do that you may eventually. But doesn't that sound fun anyway. Order a martini when you get there; shaken, not stirred! And get a hat.
