In a special event watched by thousands, he unveiled what he calls “the boldest undertaking” he’s ever attempted — a real-money initiative that will document every trade, decision, win, and loss in pursuit of a million-dollar mission. And the results are already surprising. One early beta tester tripled her investment income in just three trades.
