BetKing is unique in the sense it doesn't have many players, but the players it does have are whales. Its hard to believe there are many whales out there that will be losing the massive sums they have in the past.
How much of the profit (82% more than EV) came from unlucky whales with very high bets? And how likely is that to happen again since Max Profit dropped to 37 Bitcoin? I've seen it higher than 400 Bitcoin at some point.
