Trump’s New Currency Reset (Ad)

Trump is launching a new $250 bill - but that may be a distraction. Behind the scenes, Executive Order 14241 is orchestrating what analyst Porter Stansberry calls a total U.S. money reset, bypassing conventional legal channels under the guise of national security. The last time America reset its currency - under Nixon in the 1970s - it created an average of 1,300 new millionaires a day for over 50 years. Stansberry has identified three asset categories connected to Trump's initiative that could surge, plus his single top investment move.tc pixel

The full account follows the money behind the headlines and shows why the Iran situation may look very different than reported.tc pixel
