Well they were very generous when they launched their signature campaign, running for around many years and ended it already with total payment more than 100/300 btc l if i'm not mistaken back then. Bitsler sigcamp was one of best sigcamp which has best pay rates.
But I am confused why they limit my bet limit if I win a few bets serially. Previously, I had won a few nets on cricket then they limit my bet limit on cricket and now I have won a few bets on world cup and they have limited my bet limit on football. If I violate their terms then they should ban me 0or warn me and/or they should limit my bet limit on all of their game either sportsbook/casino. But they are not doing that and instead of that they are limiting my bet limit only on those which I make little profit.
@shasan did you reach out to the support if yes what explanation did they provide for their actions, because my basic understanding is that all we can do here is speculate but the specific reason can only be provided by support. Furthermore if you feel you were particularly targeted in the past why continue with them, unless they had resolved the past issue but if they didnt and you yet continued then my suggestion would be to pause playing there till all your issues are resolved with proper explanations.
