But SBF? The last interview I saw him give was I think with Levine; it was shocking because SBF was describing whence crypto derives its value. And Levine remarked that SBF was describing a Ponzi scheme.
For me, that interview showed two things. First, that SBF quite obviously has no morals whatsoever. And second, he's not nearly as smart as he's portrayed to be.
His whole cred derives from his MIT degree combined with his experience at Jane Street. Jane Street is a great firm, but what they do is really specific, and not necessarily the "coolest" way to make money. It's a lot of tech and infrastructure, less finance and trading chops. (The real badasses are RenTech, for example.)
Anyway, I watched a few videos that he made while working at his crypto hedge fund, Alameda. He described the strategies, and they sounded like the typical market maker stuff - arbing exchange discrepancies yadda yadda. Not the most inspired stuff.
