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

Goldman Sachs just told you what to buy (most people missed it) (Ad)

Goldman Sachs just revealed that 40% of AI data centers will be crippled by electricity shortages by 2027 - not chips, not funding, but power. Demand is growing 15% per year and the grid can't keep up. One small company makes the exact equipment these data centers need. They're sitting on $1.5 billion in orders, their hardware is already inside Musk's Colossus, and the stock still trades like a name nobody's heard of. Analyst Dylan Jovine is releasing the ticker for free.tc pixel
