You have raised a pretty valid questions, and a new perspectives.
Bet Clubs: I have checked some bet clubs, but most of them are based on the same scheme, but in some case they can even modify the odds if they bet at the same
bookmaker.
Prediction leagues: They usually relying on data, but in a long term they can not really beat the bookmakers.
Tip-sharing Platforms: This is what I was looking for. First thing in my mind was something like
polymarket, where bookmakers have their liberty to create any kind of event, and others can bet on that, but only on single events. And I also have searching for a quite while. Have find also
BetOpenly, but it's UI is quite confusing and complicated to me. Then I also have found
bet-wars, where you can actually have a freedom to create any kind of events, with multiple outcomes, and also can combine. Also you can follow others, build a community and even pick the best odds for kinda same event.
What are your experience about bet clubs, pred. leagues, and tip-sharing platforms? Which one have you tried?
