A major gold reset could be closer than people think (Ad)

For 50 years, Washington has held 8,133 tonnes of gold on its books at a fraction of today's market price. One executive order could change that — potentially triggering the largest wealth transfer into gold in modern American history. The last time the U.S. faced this combination of inflation, debt, and monetary pressure, gold climbed 2,300% in the 1970s.

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
