The investment of the bankroll is not on the Betking website and the 50 BTC Jackpot never was won.

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

Dean Nolan should part with the BTC from the ICO that went to make a millionaire while investors saw their investment in Betking tokens become useless and worthless.
Since nobody seems to have won it and no news was put out about it being removed it seems another highly suspicious piece of activity on part of Dean Nolan, that is of course unless Dean Nolan starts to tell people about his activities.
As for him buying me a beer I think it would be appropriate for Dean Nolan to publish his expenditure and allow audits of the Betking website to all investors and those that want to scrutinise the accounts.
