Trump’s issues shocking Executive Order on U.S. Dollar (Ad)

Three days into his second term, President Trump signed Executive Order 14178 a move the press barely covered. Buried inside is what some call the legal groundwork for the biggest change to American money in over a century, with a key Treasury vote potentially as soon as January 18. Ian King, Chief Strategist at Strategic Fortunes, breaks down what the order could mean for the dollar and the financial system.tc pixel

First Look: Elon’s “Starphone” (Ad)

Rumors are swirling that Elon Musk is developing a new mobile device that could rival the iPhone. It's said to be thinner, longer-lasting on battery, and cheaper to produce, with the ability to work worldwide without relying on cell towers. Former Bloomberg reporter and SAC Capital trader Josh Baylin says the evidence is mounting. He notes the FCC recently gave Musk a green light connected to his mobile plans, adding fuel to speculation. Baylin previously called the smartphone boom in 2004 and predicted Apple would sell a billion phones when others expected a fraction of that.tc pixel
