First of all, I'll just make it clear this is purely hypothetical. I haven't yet decided anything
An equity share idea is a good idea. And this way you don't even need to take a cut, you just own all the shares.
One thing is that you need to make it transparent what one equity share is worth.
Well, that is something the market would need to decide. But I would be totally transparent about networth, bankroll, etc
For instance, someone recently won almost 30 BTC which reduces our assets by that amount. But it's unclear how that would affect a share valuation (perhaps it's so fuzzy that it makes no impact, perhaps people panic sell, perhaps people buy as it's a sign of healthy activity).
And actually one thing with equity shares is that you have the chance to lose money. It's actually a completely different business model. With something like Just-dice your money is completely liquid. It's like a savings account, you make profit when the casino wins. And you give a chunk of those profits to the bank.
But an equity is completely different. What you're buying takes into account future returns it's not just based on net value. While you're not taking a 10% cut you'll be selling the premium which could be high.
Yes, that's a big difference. I would only be interested if there could be a robust secondary market, but a large amount of the value will be derived from expected future returns.
One thing I want clarification about is the difference you'll make in the company and you. Currently you have a 100% stake in the bankroll. When the company decides to sell shares will they be selling new shares or selling your shares? When the company buys shares, will dividends on those shares be going towards the companies NAV or will the be distributed to you?
I'm open to suggestions, but I was thinking that I would start off with 100% equity (what I currently have) and have the company start issuing shares, which it sells on the market. The money the company raises will get put into the bankroll, which will in-turn increase the casino limits. Then I could personally buy or sell, just like any other investor. If the company is holding shares at the time of dividends, the money would just go towards the NAV.
EDIT: I think bittrex and poloniex support having coloured coins on their exchange.
Ohh! I didn't know. I'll check that out now, that's great to hear
Edit: bittrex is out:
Note that we cannot list currencies where its primary purpose is to support gambling, illegal drug sales, or any other activity that is illegal in our jurisdiction. We also cannot list currencies that would be construed as a security such as digital currencies that promise/market profits or represent shares of a company.
Well, at least that's better than the person who said he was continually reminded of "bustabitch"
