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.
