Why I'm NOT Buying the SpaceX IPO (And What I'm Buying Instead) (Ad)

Don't buy Nvidia... Not when the AI companies that will define the next decade are selling for pennies. You won't find them on any stock exchange. The big funds already know this... Their focus has shifted to a subsegment they call decentralized AI. They're launching tokens in the native markets. This is where coins list months before Coinbase, Kraken, or Robinhood… because raising from millions of investors beats begging a handful of funds. This is the world's first open venture capital market… a teacher in Ohio investing at the same stage as a billionaire in Singapore. Watch the free training on how to access the native markets (and buy potential AI unicorns before major exchange listings).tc pixel

Trump and Bernie agree on this (Ad)

Donald Trump and Bernie Sanders rarely agree on anything, yet both are steering the country toward the same economic system, according to veteran analyst Porter Stansberry. The government has already taken stakes in companies like Intel, Lithium Americas, and MP Materials, while political rhetoric on both sides points toward deeper centralization. Stansberry has spent months investigating what this bipartisan shift could mean for investors navigating the months ahead.tc pixel
