I feel is too late to back up a currency like the dollar, because to make from that a reality they would have to first pay the Debt they have, and that amount is a joke. We are talking about a $101,515,840,000,000 dollars. And how can you back up a currency with an astronomical debt like that, Is just impossible. And that debt will stay there forever, it will only grow up because the debt is the perfect tool to make from money an infinite element. And the reality is that the world doesn't have the balls to make them pay that debt. So, it's easy for them to increase it each year.
