Mathmatically this is impossible to lose that often with high losing streaks which should happen 1 time in 500 and more occasions, for me it happens 1 time in every 30 or less occasions. How is that possible if it's a fair game? BC is a total scam site and I will put some time in to let everyone know here and at any other site.
You are an old gambler. So, you should know it very well that gambling doesn't follow the normal mathematical rules. The probability of getting the longer losing streak is very low, but you may get the rare losing streak a few many times within a short time if you are unlucky. I have gotten 4-6 losing streak a few many times within 100 bets at 82.5% win chance. It doesn't make the game unfair or rigged. BCgame won't be able to gain such reputation if their dice game was unfair. You may verify the fairness of each bet if you want.
