America’s new money explained (Ad)

The last time America reset its money, it minted 1,300 new millionaires a day. Porter Stansberry believes Executive Order 14241 could trigger something even bigger. In a new documentary, Stansberry names five assets to watch before America's new dollar rolls out and explains why the U.S. government is buying stakes in small mining companies, a move not seen since World War II. He also points to a December gathering of world leaders at a Trump resort in Miami that could reveal the new dollar to the world.tc pixel

They didn't warn anyone in 1971. This time someone is warning you. (Ad)

On August 15, 1971, Nixon interrupted prime-time television and ended the gold standard in 15 minutes - no debate, no vote, one executive order. Gold tripled within three years and climbed 20x over the following decade. Trump holds that same executive authority today, and his advisors are openly saying a reversal is on the table. There are two ways this plays out - both move gold in the same direction. A free briefing breaks down exactly what Nixon did, why Trump is positioned to act, and how to move your 401k into gold before any announcement - tax free.tc pixel
