===> I guess the answer is NO. Because the IDs are dispeared after few months of playing.....I think they will continue playing here if they won!!
There is no logic to this. A big whale can stop playing in a casino for many reasons: maybe he has tried another casino and likes it better, for example. If you have been betting for some time and know a little about the subject, you will know that winning in a casino is not a guarantee of continuing to win, on the contrary, by pure mathematics, the more you bet, the more likely it is that you will lose because of the House Edge.
