. Those whales are very competitive indeed and just imagine if there is a competition, maybe those players are not going to take a rest until they've got a stronghold of the top spot. However, as I have said, no lead is safe and anyone of them can shoot up in the leaderboard anytime.
For the new season, whales never be the first one who want to get all the attention from others players, they will be watched from side and waiting for a good moment or some luck to hit that numbers. You can assume that each week he wagered 2btc, with the 1% house edge house already earning 0.02 btc. This is only apply if he losing, but with no limit of bitcoin he will always try to get it back again and again
