The case for $20,000 gold before year end (Ad)

President Trump reposted a warning from precious metals expert Jim Rickards, tying the November midterms and America's $40 trillion national debt to a potential surge in gold prices, with some forecasts pointing to $10,000 or even $20,000 gold. Dr. David Eifrig, a 40-year market veteran and former Goldman Sachs Vice President, says an unusual plan involving Trump and two other top officials could fuel the biggest gold bull run in decades. Eifrig has shared his top gold pick tied to this developing story.tc pixel

Now Rickards is issuing a new forecast he calls a potential mid-term meltdown, one he believes could send shockwaves through financial markets.tc pixel
