The Euro is in crisis and the United States is burdened with a national debt which is spiralling out of control. All of this places the major paper (fiat) currencies of the world at significant risk. Indeed, the role of the US dollar as a "reserve currency" is under threat. As a consequence, many central banks around the world have been quietly increasing their gold holdings as a hedge against the possible demise of the US dollar. This book shows readers different ways to invest in gold and helps them determine whether a gold bubble has already developed and is about to burst or whether investing in gold still offers an opportunity to make huge gains.
