I think what he's talking about, is the stock-market equivalent of taking all of your stimulus check, cashing it in at the casino, and "put it all on black".
Of course, hindsight is ALWAYS 20/20, and if the stock market was really "that easy"... no-one in this country would be "poor".
Meanwhile, in the real world, little Timmy needs an adequate laptop for distance-learning, and Mom needs rent and grocery money.
Edit: And what Ponyo, so enthusiastically ISN'T telling you, is that if your stock-market WAGER, using LEVERAGE goes WRONG, you could be on the hook for MILLIONS, and have to sell your house, your car, etc. (The casino bet is safer.)
