As I mentioned in another comment, I think it's not accidental that SBF was pumped full of delusions of being a boy genius.
This worked great as a marketing gimmick for sure, as people love the mythos of a revolutionary company run by a tech prodigy.
But it also works when everything falls apart because SBF's delusion driven ego sucked up every morsel of attention and responsibility.
I also wouldn't be surprised if, through various means, many of his investors ultimately walked away with far more money than they started. And nobody bothers asking questions about that because SBF does such a great job of drawing all the attention.
