I listened to 10 seconds of this video, and already find it suspect. He's trading for Balfort, he's a supposed mafia guy with that fake gravely NY voice, and there is Godfather-type music in the background? Fuck off, I am not wasting another 80 minutes of my time on it.
I find this interview very informative, also from a historic perspective as he talks from the start of his career in the 80ies up to today. Interesting and skillful, hardworking guy, IMO. It just happened that he also had the mob as his clients, though he wasn't unhappy about it...
