While I´m sympathetic to a lot of your claims, I have to disagree with this one.
The current max win at the BetKing dice game is 10 BTC.

If we assume that BetKing is only allowing a max win of 2 % of the bankroll,
the bankroll would have to contain 500 BTC, which is roughly the amount of
BTC that has been raised with the ICO. Many sites use an even lower percentage
of the total bankroll as the max win. Therefore it is likely that the BetKing bankroll is
actually higher than my assumption of 500 BTC.

On an unrelated note, the daily BetKing turnover looks pretty high compared
to the last few weeks:
WON LAST 24 HOURS: $196,460

Maybe a result of the increased promotional activity? Dean owes you a beer
