My first bet on Byteball sports betting app were losses. I layed Chelsea as the maker in the bet at 1.493 and lost 493MB, ~31 USD. I laid at a good price and could have covered my bet on Boylesports.com or a betting exchange at 1.57 - 1.70 but I didn't today. I think the sports betting bot could have a big future if you could maximise the window on the Byteball desktop wallet to take up the entire screen. Much easier to see what is going on. Also I expect that if more markets could be populated over time it would be easier for users to have more choice of bets.
I think markets are removed from the app too early before an event starts, maybe 90 minutes before the event starts, and if people want to bet before watching a match they can't at the moment. I know this protects market makers from big odds movement or something like that but I think ideally the future of this is to offer in play betting with odds that move, similar to all betting websites but for know I don't think markets should be closed until they actually go in play or maybe 5 minutes before they go in play.
I think the market maker balance should be able to be used to place bets as well [ with the caveat that if you place bets and don't have enough balance left your market making bets are no longer available] . I couldn't do that today so had to withdraw my maker balance and then place a bet as a taker.
