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

Trump has issued emergency support to accelerate the rollout, and it's already live in multiple states. The Financial Times reports Sam Altman is personally calling people to build this for OpenAI. A few little-known companies control the entire supply chain - meaning anyone who wants access must go through them. Their stocks are available to buy right now.tc pixel
