but regarding the sports betting ... i haven't looked much into sports betting so pardon my ignorance. iirc with sports betting, the market usually gives you odds and then you just have to take these odds if you want to bet on a team, right?

assuming this is right: do you think trading in a simple prediction market like "will team X win this weekend?" would already be something that is somewhat similar to sports betting? obviously, my market won't be as liquid but if liquidity is the only problem, we're on a good path :)
