I also hitted larger streaks and lost bigger sums without complaining. Last monday i lost 0.39 btc. Why i didnt complain? Because it was my fault, that i got too greedy and couldnt block 20 losses at 42 % winning chance. But i saw strange things with those losing streaks: Did no one of you saw, that if you hit big losing streaks the rolls get faster and faster on autobet?
The thing is: the script, thats used by bitsler, is still a piece of software.
