Together with Sangtae who holds MBA from UCLA, Hobin produces YouTube videos on stock. He opens his first stock account and participates in the money game. Encouraged by his short-term success, he sells his house and uses his credit card to increase his stakes. He bets himself and his family’s future on the stock market.
