This sub-5 dollar stock operates next to SpaceX and Blue Origin (Ad)

A small public company trading under $5 a share operates inside the secure perimeter of Kennedy Space Center, right alongside SpaceX and Blue Origin. It holds a special agreement to use a multi-billion dollar federal launch facility for just $500, and its customer list already includes the Pentagon, Lockheed Martin, and GE Aerospace. Most Wall Street analysts have not caught on yet, but a major milestone could change that soon.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
