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
