How you made a scam accusation thread with proof? I have been seeing more and more people complaining about 1xbit and how they are scamming people. Kinda sounds like they are doing "selective" scamming.
As far as I know, there are more than few sportsbook that allows esport gambling. They were in rise ever since different companies started taking actions against egambling sites that use  their "products" or "items" (such as keys and skins)  for gambling. Maybe have a look at the lists or thread people provided over here. Make sure you see how established they are and if they have a good reputation or not.
