Iran's New Leader Just Said Something That Should Terrify Every American (Ad)

Iran's Supreme Leader has declared the Strait of Hormuz closed as leverage against the U.S. - and with 40% of the world's oil passing through that corridor, crude has already crossed $100 per barrel. History shows gold surged 571% during the 1973 oil crisis and 425% in 1979. Today, the U.S. holds 8,133 tonnes of gold valued on the books at $42.22 per ounce - while gold trades above $5,000. American Alternative Assets has released The Great Gold Reset report detailing what this gap could mean for investors.tc pixel

Read this warning immediately (Ad)

Porter Stansberry, founder of one of the world's largest financial research firms, says he's breaking the biggest story of his 26-year career. A famous historian whose books have sold over 45 million copies in 65 languages is warning of a structural shift so large it has only one historical parallel - 1776. One Stanford economist calls it 'the biggest change ever - bigger than electricity, bigger than the steam engine.' Stansberry outlines the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this shift.tc pixel
