love the idea (partly cause I considered doing something like this previously). Here are some things you could do - Give the top performers a diary where they explain their thought processes about their bets, show what wagers the top betters have made (individually and in aggregate), and allow your users to join "teams" ie "team London" might compete against "team Liverpool". Also I would specify a fixed weekly bankroll to make it a fair competition. Anyway, best of luck!
