I am still surprise that you are still holding that 15 BTC the thread has been around for more than 4 years now and you still haven't started your own dice site?
For me if you couldn't set up your own why not try to invest in the site's that are already doing well?
It is safer than to start from scratch and compete with so many popular dice site and it would cost too much to promote it and the outcome is uncertain.
There are so many gambling sites that offers such service you could try to invest in their bankroll and you wouldn't need to do anything.
Just my opinion didn't mean to offend you or anything.
these dice sites always end up running with peoples cash like dean of betking and safedice. i am never going to put 15btc into a random site. no matter how trusted they claim to be.
If that so, you can start your own gambling site. And with that 15 btc, I think it is enough to start the gambling site.
It is no matter if the site is small, as many gambling sites start from scratch. As long as you can serious with your site, I think you can do that, and you can grow your site slowly.
The matter is how serious you can build your gambling site.
But I wonder why you don't create your gambling site from a long time ago? If you build your site in the past, you can grow the site and from time to time, and you will see the site will get many gamblers.
Maybe you can also ask the other gambling site owner to know how to run the gambling site.
