It’s not about Greenland (Ad)

The petrodollar arrangement that anchored the US dollar for 50 years quietly expired in June 2024. Since then, China has cut its Treasury holdings by 45% from their peak, and BRICS nations offloaded $47 billion of American debt in a single month. The Trump administration has responded with a $12 billion critical minerals stockpile called Project Vault, equity stakes in miners like MP Materials and Lithium Americas, and a push to secure resources from Greenland to Ukraine. Porter Stansberry lays out the full story in a new documentary, including five companies positioned at the chokepoints of what he calls Trump's New Dollar.tc pixel

Do this before December or regret it (Ad)

Porter Stansberry believes President Trump will use the December G20 Summit in Miami to unveil a radical monetary reset tied to executive order 14241 - one he says could draw a sharp dividing line between prepared investors and those left behind. The last time America reset its money - under Nixon in the 1970s - it produced an average of 1,300 new millionaires per day for over 50 years. Stansberry's new documentary names a core group of assets he believes are positioned to surge as Trump's new dollar rolls out. Watch Porter Stansberry's full briefing and get his three steps to prepare before December.tc pixel
