The trade I’ve been waiting for since 2011 (Ad)

Ross Givens, Director of Research at Traders Agency, is calling for gold to reach $10,000 an ounce this supercycle - and says that may be conservative. Billionaire Pierre Lassonde has argued for $19,000. Former CIA advisor Jim Rickards targets $27,000 based on a federal revaluation of the gold supply. But the bigger opportunity may not be gold itself. A 'backdoor' gold-linked asset has historically multiplied gold's move by 10x or more - returning 846%, 1,668%, 1,847%, and 1,915% in the last supercycle.tc pixel
