The basic house edge of letsdice.com is 1.98% (Since we're trying to have both on-chain and off-chain mode, which is compatible to SD).
However, here's the main point: out of 1.98%, 0.48% goes to the JACKPOT (to players), and 0.5% goes to the players' referral rewards (to players). Therefore, in the end, the house only keeps 1%.
Wait so your telling me that the 0.48% (which amounts to a little less than 25% of the house take) of the pot goes to the Jackpot, which more than likely going to dusters playing your site for a sahosti, because the amount of rolls increases your chances of winning.
Then you telling me 0.5% (25% of house take) goes to the players referral rewards, namely the player who did the referral.
Then the 1% house take (50% of profits)
So lets say I refer Doog who decides to make a run at your pot and loses 200 BTC, I get 25% (50 BTC) of it with referrals, the Jackpot gets ~24.5% (49 BTC) and the house gets 50% (100 BTC)
If I was an investor I would be pissed, because they are taking the real chance of losses with investment and not truly reaping rewards, because imo it limits your inticement of playing with 2% -ev, this should also keep larger players away from your site, imo.
I actually get the whole referral system as this is usual in casino sportsbooks but at that rate its almost ridiculious imo.
Now for someone like me who rarely plays "dice" games I find a couple of dump big bankroll guys and send them to your site maybe its a good deal, or I might just run you bot on weeks on end till i roll XX.7777.
Imo if you change the 1.98% to 1.098% with jackpot at 0.0498% and refers at 0.05%, that actually attracts interest and whales wont see this as a disadvantage.
**Unless of course someone makes the refers all to themselves, for larger players who did not get referred**
You missed one thing, to win the jackpot, your roll must have a bet of 0.1 BTC or higher. So, no dust bets will ever win it. (Read this on the site)
