I can definitely confirm that you can't win more than a couple hands in a row on this site. Also, they make you lose after you win a certain amount, but that's basically every bitcoin casino.
That is not the case with every bitcoin casino . Considering only blackjack , I haven't seen people on other site argue about the casino being rigged. its on on Nitrogen, you have claims by people. Someone reallly needs to look into their provably fair algorithm as well as their 3rd party provider.
