A letter from Shannon Stansberry (Ad)

Porter Stansberry nearly canceled the entire project. When he first saw the claimed returns - only one down year in nearly two decades and total gains of almost 2,000% - his immediate reaction was disbelief. It took a trusted friend's personal vouching for Emmet Savage and a face-to-face trip to Ireland to change his mind. The full documentary, Investigating Project Prophet, is now live.tc pixel

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
