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.
