It looks like the user with id 22123 has outdone himself by collecting over 29 million lottery tickets this time. Honestly, I've always wondered what exactly motivates the users (whales) who wager so much. I doubt such users do it just for fun and hope for their luck. They probably have some special strategy that minimizes losses due to house edge and allows them to profit from both the daily leaderboards and the huge number of lottery tickets and RPs.
