What the article doesn't adequately disclose is that Diehl has a phenomenal commercial conflict of interest as the CTO of a "private blockchain" company that considers public blockchains its primary competition.
This makes sense to me in the sense that as far as I can tell SBF and Alameda's claims for the origin of their wealth is obviously false: He claims he made billions of dollars on an arbitrage with Korean exchanges and the rest of the world. Price differences existed, but with extremely small volume. If he claimed to have made millions from it I would have been highly skeptical, but billions? And during a major crypto down market to boot-- not a time when any idiot in the space could accidentally make a fortune just by having exposure.
But if that trade wasn't real where did the money come from? One possible answer is that the money never was: maybe it was always just marked up balance sheets holding multiple times the circulating market of illiquid and close traded tokens-- all a great big fake it until you make it.
