I don't really see the benefit in creating an investor risk adjustment option. The site already has a fairly large bankroll, do we really need to accommodate larger bets? Why create a confusing and hard to implement (from my understanding) system that isn't really needed?
Why adjustable chances when just-dice could be a simple even bet site?
And what confusion? The gambler wouldnt see a difference at all and for investors that dont care wouldnt change anything at all too. They would stay at 0.5% as usual. But for all others there is a chance to adjust.
Its not hard to implement. When the profit per person really is calculated while divesting then the profit would be calculated by the set risk level. Before that at investing the playable max profit is adjusted matching the investors risk level too. Doesnt sound like many more calculations to me. I think even fully free setable risk levels could be possible. Though im not sure why someone wrote about too much calculations then. As far as i see it at the moment its only an adjustment in code, a database entry for risk level of every investor and a database field for the playable max profit for the house is new. Adjusted at every in- or divestment.
