I wouldnt doubt that the system just jacked u... Hard to do that in 50/50 its like getting hit by lightning.

U cant even dispute it since they will throw the math book at u.. I wouldnt doubt if these sites detect martingalers and screw the ones over who bet alot of money... I bet u did lose alot and i bet the site got u amd not math.. Although it doesmt always have to be that way just another reason not to use it
