Ray Dalio: Buy Gold. Get Paid. (Ad)

Ray Dalio, founder of Bridgewater Associates, is urging investors to hold 15% of their portfolio in gold and crypto as U.S. debt continues to climb and fiat currencies lose purchasing power. A little-known $15 fund is already converting gold's momentum into monthly income - as much as $1,152 per month. No gold bars, no mining stocks, just consistent payouts.tc pixel

A letter from Shannon Stansberry (Ad)

Porter Stansberry nearly canceled the entire project. When he first saw the claimed returns - only one down year in nearly two decades and total gains of almost 2,000% - his immediate reaction was disbelief. It took a trusted friend's personal vouching for Emmet Savage and a face-to-face trip to Ireland to change his mind. The full documentary, Investigating Project Prophet, is now live.tc pixel
