Sorry for I didn't think it clearly enough. Yes for a default of 0.5% max win with a 1% edge, it's impossible for a player to take the bankroll through a single bet, it only happens when the max win is 1% of bankroll under 1% edge. But the chance is just too tiny which is like a jackpot

Will you be allowing investors to specify the maximum percentage of their investment that they are prepared to risk on a single roll?
It's possible that some of them wouldn't want to risk 50% of their coins on a single roll no matter how high the house edge was.
We don't think so Doog, it would be complicated. It's also doesn't make sense if a player bet on a super high HE, just as you said, in that case they'd be better off betting on another site with higher BR.
So, our current idea is to cap the HE between 0.5% to 10%, depends on their profit on win / bankroll ratio (we'd like to keep it at half kelly). Do you think this would be a good idea?
Another thing to consider is that the site will be deciding a bet's HE in real time, so if there's an invest/divestment when the bet request is sent from the client to the server, there might be a slight difference between the HE shown on the client and the server's calculation.
And Doog, if you have the time, would you be interested to test this new feature when it is finished, but before it launches to the public?
