It's always about whales who know what they are doing. They may win or lose, but they know when to get in and when not to get in. That is how they became whales in the first place, if they knew that it would be a wrong move then they wouldn't do something like that at all. This is why I have to say that it is better if we just leave them to be, and not even try to come close to them.
I know there are a lot of people who would wager the minimum and hope that they could end up wagering for a long time without running out of money, maybe even end up with a big win to keep it going for a long time. But if you are not a whale, do not risk your money like that ever.
If you most often visit the leader board one of the starts up players RealWinner is always on the leaderboard and after that is most of the time private users currently there are some player who would like to catch up RW too in the board, and recently seeing DewArr again. Currently, in the biggest competition, RW have the most votes against HKS2 holding the rank 2 and 3.
