Trump's gold order: the announcement they won't put on the front page (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
