But if I'm not mistaken, has anyone ever won bigger than that on rollbit
Yes, Casino use this big wins for advertisement purposes because it can attract other players to play in the casino and increase the trust since they are paying out huge amount. I doubt too that this will hurt a million dollar casino while this whale is still playing. I’m sure he already loss a lot before he manage to win that jackpot considering how huge his bet size.
This is how they market their selves because those big wins is instant attraction for speculators or all gamblers in their community so for sure once there's announcement that there's a player win that huge amount and they paid that instantly for sure the level of trust and hype will be huge factor for them to gather more players. We don't know yet if that player lose a lot of money before hitting that but one thing is for sure the player who win such huge amount is happy and hype up for more so maybe we can see more bets coming from him and people following his tracks.
