OK, thanks for clearing that up.

To further clarify:

You sell 30% of the company (BK) to investors for 2000 BTC (supposing again that the ICO sells out)
You (DN) keep 70% of the company, and 2000 BTC.

So BK has no BTC, DN has 70% of the shares and 2k BTC, and the investors have 30% of the shares.

Do I have it right so far?

If so, let's proceed. I'm guessing here, but is this how it works?

* DN gives BK an interest-free loan of 2k BTC to use as its bankroll.

* BK pays its expenses out of the 2k bankroll. The bankroll grows and shrinks as players bet.

* Each 3 months (or however often dividends end up being paid), you check whether the bankroll is over 2k or not.

* If it is, you pay out the excess to shareholders. 30% to the public investors, 70% to DN.

* If it isn't, you pay no dividends for that period and wait for the bankroll to grow back over 2k before paying anything out.

* If BK is ever sold to a new owner, it pays back the 2k BTC loan to DN. If the bankroll is less than 2k at the time of sale, the shortfall is made up from the sale price so that DN's loan is repaid in full.

* After repaying the loan, the money left over from the sale is paid out to the shareholders. 30% to the public, 70% to DN.

I don't think I've seen you refer to the 2k in BTC's bankroll as a loan from DN to BK, but I don't see what else it could be. It doesn't belong to BK. It belongs to DN, who sold 30% of the company in exchange for 2k BTC. Is it a loan? Is it interest-free?
