That's lower than most bitcoin/altcoins dice websites!
Good decision!
Btw, your faucet level is too difficult to increase. No one will get level 24 because earn ref commissions over 7.5BTC and wager 3000BTC is impossible.
What you should decrease is the difficulty of account level, house edge is not important, Primedice has 1% house edge but it's still most popular. And dadice's level is much more reasonable than you. I am level 22 and my faucet is almost 6k sat.
One thing is for sure... we are not some kind of giveaway company, that can give out a large amount of free coins to every user. Our goal isn't that everyone reaches max level, because we would bankrupt if it would happen.
But for loyal and good players we offer bigger faucet than to new users.
For good referrers we can discuss about bigger referral commission, just write us an email.
