Besides there is still the World Cup pool which is still only less than 30 people. There's nothing to prevent them from joining that, right? Maybe we can see you join that? https://bitcointalksearch.org/topic/sportsbetios-world-cup-prediction-sign-up-0002-to-join-02-in-prizes-5419161
there is something to prevent users from joining that pool, an entry fee
because most users do want to pay to compete, they want to have it for free, and get rewards, but that is simply not possible always
with all said, these paying pools, with all free bets, sponsorships and rewards in the end, without cut from entry payments for organization really seem as a bargain, and have real value for users, at least I see it that way, and question myself how it is possible that there is no more than 20 participants in all beside EPL
