It’s simple, You lose your money then you shouldn’t blame the casino regardless on where they operate if their game is fair. The blame should be directed to you alone since you are responsible for your action not Stake that didn’t force you to play.
Just file a case and let a judge decide what’s good for you instead of threatening the casino for a lawsuit.
If you’re case has some merit on it then just pursue legal action instead of convincing us to your long journal which simply tells that you lose and want to blame Stake for letting you play.
