What is Hushpuppi's source of income

[Borrowdale Barron]

What's the source of Hushpuppi's money? For instance Aliko Dangote we know he is into cement, sugar, and so on, but which business is Hushpuppi into?

It's still not very clear how Hushpuppi makes money. I don't understand why he doesn't mention his investments so often and that to me raises red flags.
