From the man who predicted 2008 crash… (Ad)

Porter Stansberry, founder of one of the largest financial research firms in the world, says he's breaking the biggest story of his 26-year career - an economic shift not seen since 1776. From the government taking stakes in Intel, Lithium Americas, and MP Materials, to sweeping political changes reshaping the economy, Stansberry argues a rare 'New 1776 Moment' is already underway. One Nobel Prize winner calls it a dividing line for all of society. His presentation covers the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this shift.tc pixel

What is “gold skimming”? (Ad)

Former $900 million hedge fund manager Larry Benedict has developed a strategy he calls Gold Skimming - a way to target cash payouts from gold markets without buying a single ounce, mining stock, or ETF. With a reported 73% win rate across 19 trades and potential payouts of $2,975, $3,781, and $6,786 in a single day, Benedict has put together a free step-by-step walkthrough showing how it works whether gold climbs or pulls back.tc pixel
