Claiming to have only $100k in cash could be true. Maybe he simply forgot to mention other valuable assets worth $700M like yacht, cars, properties, egg farms etc. 

When people ask about my net worth, I also tend to forget mentioning my other valuable assets like Pokemon cards, toy cars, or my mansion made of cardboard boxes behind Wendy's. Lol
