Today watching high rollers on your site I thought you were hacked.

It would be nothing unusual if those bets were made with 1.1x or less, but all of them were made with 7x multiplier! I mean, how is it possible to have so many greens in a row with 14% win chance?
Only later I realized that the guy was performing a kind of martingale and only his winning bets were appearing in the HIGH ROLLS. And I thought I was witnessing The Return of the Hufflepuff.
