There is a big difference between an equity investment and a loan. Perhaps you should post in the lending section instead.
In any case you are almost certainly wasting your time. A reasonable investor does not loan anonymous persons $10,000–let alone $30,000–in unseizable currency.
The bigger issue here is that even structured as a "loan," this is a horrible deal. Again, investors front 100% of the risk for a small portion of the profit. And if someone came to him to buy the site, he'd owe you absolutely nothing, getting 100% for himself.
It's just a really bad idea: his knowledge of the sector isn't nearly enough to warrant such a high risk with low rewards. If he had many highly successful sites in his portfolio that he built up, it would be different. But he doesn't. As such, most of us who WOULD possibly be interested would absolutely have to get equity, and with that would come some control over its direction.
Okay i understand your concerns so I will offer 50% of the profits and 50% equity to the investors which will be divided out between the investors equally according to their size of investment. But i do want the option to buy back the profits sharing/equity from the investors eventually without the hassle of the investors not wanting to sell, thats the only problem i have is i dont want to not be able to buy back the rest of the business. So if the investors can agree that no matter how big and successful the casino may get i will be able to buy it back according to the value of the share of the business at the time i am able to buy the shares back then i will be fine with giving up half of the equity for now. If you have any other concerns please feel free to comment them below so i can address them as soon as possible. Thank you.
You seem to want the best of both worlds.. Investor takes all the risk and you take all the potential (forced buybacks). 50 BTC also would not be enough to get this going (by the way), you really should have at minimum 100 BTC set aside for a bankroll or its not even worth attempting.
