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

60 years. Zero competitors. (Ad)

One company has spent 60 years developing an energy source the International Energy Agency estimates at 140 times global electricity demand - with zero competition. Last year, their crew drilled in 16 days what the government projected would take 64. Now Google has a 15-year deal locked in, Bill Gates has committed $100 million, and the Pentagon has made it a top priority. On August 18th, a new Washington policy adds another advantage rivals cannot match.tc pixel
