Nakowa has stated that he will never play again since the max bet has been lowered.
As an investor, Are you happy with lowering the max bet?
You say that he has 13,000 BTC of investor's money, did he win that or steal it? If it was won, then it is wrong to call tha tinvestor's money, if it was stolen, then you are correct. The investor's knew the risk of where that money was going and chose to make the deposit anyway, therefor it is his money and not the investor's. If he had lost, would you have said that you had his money? No, it would have been your money.
But back on subject, I did not quite follow what happened and the events that led up to the max bet being dropped. This is a weird instance though. Technically the owners of the site are the investors and should be able to make decisions like that based on proportion of money invested. But this is bitcoinland where company officials are not elected, and can do whatever they want with investors money, with little to no repurcussions.
Since this is bitcoinland I would say that since Dooglas started the site, he should be allowed to do whatever he wants with it. That is not how the world is normally run, and he should probably have asked or created some polling system to get an idea of wha this investors thought.
