Nope, they don't need two different providers for that. Two different casinos, yes, quite likely. Two different providers? No. One provider that facilitate casinos with sportsbetting is enough. They can collect the data of the bets, as basically all data are being analyzed by them. And OP, apparently, played in tons of casinos. How small is the margin that amongst those casinos, two or three or four of them are with Betby?
