Are faucets, referral commissions and promo costs all deducted from the investor profit? or is it paid from the sites cut?
It is paid from the site's cut.
If you look at all of the casinos that operate on a crowdfunding basis, then you'll see that the site's cut is split into a)promotion of the site, b)running the faucet and c)paying for server fees and hiring people etc.
It is definitely not from the investors.
Ethan could pay it himself as well.
this is true for yolodice. cryptogames for example deducts the faucet from the investors profit.
