This is the reason why most prediction betting platforms can't sustain the interest of the gamblers. If they will deploy another game aside from prediction betting game, players may have other options while waiting for the results of their game. The platform needs to offer other services that will make their players stay while waiting for the results. Otherwise, it is really hard to keep up with this kind of gambling site.
That is why prediction gambling sites like sports betting can sustain their business model because they have many games they can offer to their users, they can play dice game, slot while waiting for the outcome of their prediction, what I mean is there should be variety if they want to be sustainable in a long haul.
