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

If you keep cash in a U.S. bank account… read this NOW (Ad)

Since 2020, U.S. banks have been required to keep zero percent of deposits on hand, lending out nearly every dollar while paying savers just 0.04 percent interest. A new law, the GENIUS Act signed last summer, has cleared the way for a different kind of money to emerge this fall, one that could offer savings rates up to 6 percent. See what Ian King, Chief Strategist at Strategic Fortunes, has uncovered about this shift before it goes live.tc pixel
