I also just realized you have negative trust, I never had problems with nitrogensports, what happened?
Based on people feedback many problems from some players on that site who lost their bets when the team he picked won. I don't know if it's true because while I was playing there I didn't get any problems. My advice when making a bet should be to share your bet slip or screenshot it so that can be recorded and can be proof.
Hmm, I don't know, one of the feedback is that the site does not have proper protection against cheaters/abusers, however that doesn't mean they are scamming, in fact they are the ones affected by it in any case, no? Nitrogensports basically got a negative feedback because people abuse their system, makes no sense.
