1. What are the first things to put in place before starting?
2. What are the strength and weakness to consider with gambling platform?
3. Can you hire a person to be in charge, for the business management of the gambling platform?
4. Is it a profitable business base on your own experience or from what you have seen others achieved from establishing one?
I'll try to answer it:
1. Doing some research is always the first thing to do. Your target audience, how will you make yourself unique and different from those competitors of yours, gambling licenses, and of course, a reliable marketing team and and a good marketing strategy. You will need those if you want to start a gambling platform business.
2. How accessible it is? Is it accessible worldwide? Are there no restrictions to it? Can we live games in your platform? As for weaknesses, something like the competition especially now that online gambling is becoming more and more popular, more and more gambling platforms are being created.
3. I don't see any reason as to why you don't need to hire a person in charge of your gambling platform especially if that person is something you considered as trustworthy. As long as he can do what he needs to do then just hire, but if you can do it yourself then just do it.
4. I believe it differs. The profitability of a gambling business depends on how good they are on marketing of course and many more.
