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
