i just got a 19 loose streak with 49,5 on Bitsler, the thing is these lose streaks will eventually happen
It seems that you have faced some real loss indeed. But do not get worried about the situation. You can leave blister and go for some other option that would help you to attain the lucky streak which actually happens! First you would have to compensate the loss in some other way because this kind of situation does cause a lot of mental stress and then sign up for other casinos to try your luck again.
People is too superstitious , they think certain pattern can exploit the system but actually it is not.
They create a bot ,run it and for once or twice tried it feels work to make you win , but i am sure it won't run smoothly to give you a constant profit.
Provably fair and house edge there to make sure casino and players to win alternately but -EV makes us as a player to lose more often in the long run.
