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

These gold assets are priced for $1,800 gold [it's over $4,000] (Ad)

Gold's major miners are generating record free cash flow, with margins as high as 75 percent even after gold's pullback from highs above 4000 an ounce. Yet top junior mining assets remain priced as if gold were still stuck near 1800 an ounce, a gap analyst Garrett Goggin calls the Golden Anomaly. With record cash on hand, majors may soon be forced to buy juniors to secure future production.tc pixel
