Some of the bets are not just single games, but the outcome of a whole tournament. And ongoing revenue is only 1%, which relative to the other 99%, won't be so enticing after customer growth has peaked. Eventually, the reward from a "retirement attack" becomes very enticing to an anonymous biz operator (and easily blamed on an admin account compromise). Its quite dishonest to claim that "money cannot be stolen or seized by anyone" just because the bets/order books are decentralized. The outcome admin/judging is still centralized. Whoever controls the judging, effectively controls the funds.
