Agree with the gentlemen above, this doesn't sound appealing to anyone especially gamblers who usually asses their odds of profiting on a bet before getting in on it. You would need a massive amount of transactions buying/selling the token just to get a viable amount of transaction fee to be pooled in as the jackpot prize. I guess the question would be will your team able to get enough crowd to buy the token and trade them 'cause if not then you guys better think of other utility for the token or rather better way to generate the prize pool.
