Trump's New Dollar (Ad)

Porter Stansberry says President Trump has signed an executive order initiating what he calls a full U.S. dollar reset - and most Americans don't know it's happening. The last time America underwent a monetary shift like this, under Nixon in the 1970s, it minted an average of 1,300 new millionaires a day for over half a century. Stansberry has released a new documentary naming the assets he believes are positioned to surge as a result.tc pixel

Elon Is Quietly Doubling Down on This Bizarre Asset (Ad)

Yahoo Finance reports this technology 'May Unlock $400 Trillion' - and Bloomberg calls it 'unavoidable.' Elon Musk has been quietly doubling down on it, even attempting to deploy it during his time at DOGE before being shut down. Investing legend Jeff Brown - who identified Bitcoin, Tesla, and Nvidia early - has spent six years analyzing this sector he calls 'W.T.E.' He believes it could be 90 times bigger than AI and 1,900 times bigger than Bitcoin.tc pixel
