Its not a scam. That's called luck.

I do have worst records than you do.
72% win chance. Then I have 13 lose streaks, then 1 green, then another 5 red. So in total, i lose 18 times. But I didnt lose, because I do gambling manually. Its because I have to outsmart my luck. And that's why I make a living out of these "scams". I play on bitsler btw.

You can't expect a perfect win in gambling if you the have chance to lose.
