As for the calls to "change something", if he's cheating then limiting the maximum bet won't stop him winning, and if he isn't cheating and is just lucky then limiting the maximum bet will only slow his inevitable losses. I don't see how it helps in either case.
One thing that I can change that will protect investors is whether the site is up or not. If I take it down they won't lose any more. But I suspect that most investors wouldn't like that decision. They want the site to stay up so they can win their coins back again. The ones who want this to end have the option already of divesting.
I'm quite tempted to just give up on this whole thing. It looks like the site is simply at nakowa's mercy. He's promised me in the past that he won't play any more, but never sticks to his word. So what do I do? Continue to let the investors take these horrific losses?
I am a small investor and love just-dice, thanks dooglus for making it possible for small fry like me to play with you.
Now that we know Nakowa's basic system - willingness to absorb large losses while waiting for a targeted win number - it seems like investors can now design a counter strategy, for example I bailed out today for his final run of winnings. I am not anti-Nakowa, I'm glad he plays at JD but I appreciate a lot of the discussion and analysis in this thread that has highlighted he is not superman or supremely lucky, he's got a very sensible cash management strategy and JD's low 1% edge gives him a decent chance to pull it off.
I don't think he's cheating and I don't think you should do anything drastic like change the max bet of the site. Personally, I'd increase it, but I have not run the analysis you have.
What would help me as an investor is some kind of ability to put in a stop loss order, e.g. if my investment balance is < X then divest X % of my investment balance. However, I imagine that would be hard to program and result in a lot of variability in your investment total which you probably don't want. But right now I have to "lucky" enough to be on when he's on and manually monitor my balance and try and get out before I lose what are for me very hard to replace coins.
When the site had 50K btc invested you said you had too much investment, what in your mind is the ideal level of investment?
Please do not give up! Your site is one of the best things about BTC and you are a great member of this community.
