I don't think that they're going for a gold backed currency, Max Keiser's theory of a world 'digital' currency sounds a lot more plausible they'll probably blame paper for it and then claim that they need to digitise everything in order to keep to their targets better. Basic rule of keeping your wealth is this, don't invest in anything that is easily controlled by governments, especially if it's under control of the U.S.

Going for a gold backed currency would actually be a responsible move, but good luck getting any of the current leaders to do that.
