Jordan Belfort on Monday dipped back into his old persona in a video posted to YouTube in which he reenacted a scene from Wolf of Wall Street, which was based on his 2007 memoir. In the video, which runs nearly three-minutes long,the one-time New York City multi-millionaire stockbroker encouraged (mostly Reddit) stock traders to not be intimidated by hedge funds and short-sellers while also taking shots at the app Robinhood, which limited the buy of GameStop shares last week.
