Have you considered the possibility of acts from authorized insiders?

This is crazy if we keep in mind the fact that to get 39,9 million lottery tickets, you need to wager no less than 199 BTC without any bonuses. It's also worth noting that this user has won 4 of the last 10 daily jackpots, and he wagered over 35 BTC on the last leaderboard. Honestly, it looks like the guy who won the last round of the Lambo lottery has a gambling addiction.

- Either sick or healthy, it has a lot of Whale's oil. Or should I say Shark?

He could be hedging is my first thought, gaining a bonus elsewhere for high revenue etc.  Odds can be uneven for the same event, which is potential arbitrage.

I dont ask for much, I just want to be the person who referred such a big high roller.   This has to be the advantage to reviewing sites or running a directory linking sites that you can refer people commonly who are looking to bet on any of the sections offered.   Sports bets has to draw in quite a few people surely.

I dont reckon there are many authorised insiders, its probably easier on security to have less people thats the model I assume is being used.   It can be taken too far though, I remember one exchange that fell over which only had 1 person with keys and he died from a bad stomach condition.   Though I need to double check as I think if they found out he was actually alive but had fled a mtgox type scenario.

Heres a quick google, crypto is never short of drama thats for sure:
He is still listed dead at 30 but anyhow it seems best that only Flamingos should attempt to stand on one leg
