Betting exchange is a platform for betting between players on sports events. There, a player can suggest betting – choosing a particular event, then offer his/her coefficient and the sum of bet on a particular result (in this case you sell the bet, acting as a bookmaker). Or you can accept the betting conditions offered by other players – to buy the betting. This way a player becomes a participant of the purchase process, where betting odds are goods. Consequently, sports betting exchange is a mediator, providing the players with a service for such purchase. All deals are performed on the betting exchange without commissions.
