If I understand the new terms correctly the fee is also over 50% unless you withdraw from the bankroll at an all time high.
The commission is only charged on net profits, i.e. whenever the bankroll earns "new" profits above its all-time high. In fact a commission on profits is favorable for investors in this regard: You only pay a commission on the actual profits you have earned, whereas with the commission on wagers it was possible to have paid commission on expected profits that you never ended up earning.
Well,
I think you understood what I was trying to say very well.
Lets say a customer loses 100 btc, you charge investors 0.5 btc. Now the customer wins 100 btc back. Result: customer is breakeven, investors lost 0.5 btc, you gained 0.5 btc.
Yolodice had a similar system with with 15% and then 25% fee IIRC, but only took the fee once a week, which makes it much better for investors.
