Investing less money doesn't change the risk of ruin (ie. of the site going bust). Whatever you invested, you were risking 1% of it per roll.
I have temporarily set the max profit to 0.25% because with it at 1% nakowa was able to take huge chunks of the bankroll over and over, as he has demonstrated time and time again. To make matters worse, each time he takes a chunk of the bankroll, more investors lose faith and divest, resulting in the bankroll shrinking even faster.
Risking 1% of the bankroll per bet turned out to incur a much greater risk of ruin than I had anticipated, and so I made the change to 0.25% in an attempt to prevent ongoing huge losses. At no point was it intended to be "the solution"; it's a stopgap fix until I can put something better in place. I need to seriously reconsider allowing investors to somehow set their own risk level. If some want to risk 0.25% per bet and others want to risk 1% then I don't see why I shouldn't let them.
If nakowa continues to win, the 1% people risk going bust, while the 0.25% people gain an ever increasing share of the remaining bankroll. Eventually all remaining investors (the cautious ones) will be risking 0.25% and we'll be back where we are now, and the 1% investors will have had the chance they're asking for - risk big to win big.
If nakowa does blow up one day, the 1% people get the lion's share of his losses, which they will deserve for 'keeping the faith'.
Of course, maybe he'll never return whatever happens; who can say? I know he has said many times before that he has quit.
Dooglus, thanks for your (as always) level-headed and professional response. Emotions are certainly running high.
Would you consider raising the max bet to 0.50% as a compromise? It might allow Nakowa to come back, and give the 30,000BTC investors a chance to recover their losses. I assume it will take you weeks or months to roll out the custom-risk feature and Nakowa will probably be long gone by then.
Also, would you consider that it would be good idea to warn gamblers ahead of time before making big changes like the max bet?
EDIT: Rumor has it that Balotelli was in the middle of a martingale strategy when the max bet was changed and ruined his play. To set a precedent like that is terrible for the site from a gamblers confidence perspective and very bad from a professionalism point of view to do it without warning.
