I researched gambling sites for 7 years and came to a disappointing conclusion - 99% deceive users. I used tracking software.
The proof of fair play is cheating! From personal experience - when I made the ninth bet and lost, I checked the hash of the bet seed and it showed me the result (attention!) - the eighth bet. To many, this will seem like a trifle and a browser crash, but it's not!
This is a hacker's method and it's called packet interception!
And here is another trick called ,, script error, in the picture below, you will see my losing streak of 13 bets, however, probability theory says that you can't lose more than 11 bets!
