it is really difficult (technically impossible) even for a whale to be profitable in such a situation because the dealer (the casino) always has an advantage that is a small percentage.
and above all, on casino games, it is mathematical that the more you play the more you lose ... the statistics say so.
https://knowyourluck.com/roulette.html example with roulette, and this applies with all games (the in-famous RTP).
Then maybe someone wants have the pleasure of playing a "big hit" like that, but I don't think they do it for "earning" ...
betting hits and its true that not all would really be going after about earning specially for whales.For sure most of them or majority are aware on how HE works but well its their money after all whether on what
intent that they do have in mind then its up to theirs whether they would really be playing on that kind of behavior or not.
their money, their rules! as simple as that. but i can agree that when you happen to play like for example in crash, and you will see someone putting up like $20k, and lost. just wow! wondering what they are feeling in those few seconds, and realised they lost that amount in one snap. but guess what, we'll never know if we are not that person. some can spend huge amount without battling an eye. but for most of us here, it is like our ticket to survival for the next few months.
Basically they have so much money that losing 20k is not only not going to affect their lifestyle at all but they are not going to lose any sleep over such loss either, so we cannot judge their reactions using our standards as they are completely different and their approach to how they manage their money is different as well.
