Okay. Let me try to make my point clearly here.
I commend your effort at succesfully executing a Steem-blockchain based casino where people can play (specifically BlackJack) right in the Steem platform. Dividends and staking issues aside, that is an accomplishment. If I had just stopped playing before the staking issue (when I had won ~ 100 Steem and bought some SteemMonsters cards) I would have been happy. Shame on me.
Having said that, "gambling time" is "fast time", and so a glitch like the staking one on Steem Keychain is something that YOU are responsible for. You can't expect the PLAYER to take responsibility for "contacting us on Discord" because of a technical error which OTHER players had, and which challenged the player's ability to make an informed decision.
I don't think that having a referral program for a gambling site on Steemit is an ethical decision. I am proof of this. I had NO INTENTION of gambling on Steemit until I saw the post by 
I STOPPED playing the Kryptogames blackjack two days ago, as I did an A/B experiment with the PRIMARY Bitcoin casino I have successfully played on in the past : https://bitcoinvideocasino.com I deposited 0.05 BTC two days ago and the process is much more enjoyable, and seems to be MUCH more in like with true "feel" of BlackJack. Playing blackjack has a RHYTHM to it, and I spent most of the time on YOUR platform clicking the buttons to confirm every transaction, and that throws off the game complete - not to mention the fact that I STILL believe your odds are heavily rigged. So instead of chasing "dirty money" on a "dirty platform", I will now use my 0.05 to chase the dirty money with "clean money", and if I lose that then "shit happens".
It's obvious that other people commenting here are coming to generally similar to conclusions to mine (that is, that "something just ain't right" with this), and so based on the consensus I have voted with my feet.
That's my two cents.
Good luck.
