In the past years it was different, people who could build a provably fair engine were able to have their own casino, but now we are playing with new rules, the casinos must have a license and games providers, and that's what people are looking for, and i don't say is something bad, the gambling experience on stake compared with the gambling experience on satoshi bones is enormous.
But getting back into the topic, i would like to read some nice histories from the community, those who only dream about their own casino, and those who make their dreams come true.
1. You need to have consistent amounts of money to invest.
2. You really need to know a lot about this business.
3. You need to surround yourself with experienced people who can help you lead the business.
Overall, there are many variables and it's not as easy as it looks to make money out of this. If that'd be the case, we wouldn't see so many online casinos shutting down, some of them after only a few months.
If the first three criteria are met and you can handle many sleepless nights, then give it a shot!
