Ron Paul, Bob Chapman have been on about this for sometime.
Here is a small part from chapmans latest article,
We are hearing more and more about digital gold as a private-bank solution to potential devaluation of fiat currencies. The May/June issue of the CFR’s, Foreign Affairs magazine, Brenn Steil a senior fellow and director of International Economics, who has been on loan from the parent Royal Institute in London since 1996, says digital gold, “although a niche business at present, gold banking has grown dramatically in recent years in tandem with the dollar’s decline.” Mr. Steil was the Illuminist who drew up the plans for the North American Union and the Amero. If there is digital gold out there somewhere we haven’t heard about it.
The new approach to a world currency obviously will be digital gold. This way they can introduce a one-world currency backed by gold to make it acceptable to the world public. The digital nature means government would know every aspect of your financial life and would control you and your country. The gold storage would, of course, be controlled by the Illuminists. The elitists have come to the conclusion another fiat currency is not going to be acceptable. This is why JP Morgan Chase, Citicorp and Goldman Sachs talk in terms of $2,000 gold and UBS projects $2,500. Historically such benchmarks are usually and normally exceeded by prices from $3,000 to $7,000.
Steil says countries should abandon monetary nationalism and embrace a world currency.
