So this is like Just-Dice's nakowa incident right?
Some lucky whale comes in and puts the site profit into negative territory?
Very little like it in terms of betting. Nakowa didn't flatbet thousands and thousands of bets.
Sometimes that's just what he did.
He must be generating a ton of seeds and then calculating which ones will be profitable. He keeps pausing his betting every few minutes and each time he comes back his bets are winning again.
That would imply the player can predict future random events. If what you say is true, we're all in trouble. Cryptography would be broken as we know it.
I think the suggestion is that he can see the server seed, and so can calculate (rather than predict) the future.
