Anyways, I expect OP to have great customer service on his platform to avoid withholding any issue that will arise as those are what makes the casino's reputation good or not.
if the OP is a gambler who has been playing in big casinos for years. Of course, he will know what the players want. like his experience when playing in one or several casinos.
it is a good capital for setting up his business. due to experience as a player will help him in developing his business according to market demand. as well as the marketing strategy that will be carried out.
Yes you are right that mate as we all know that once a gambler launches his/her casino then he already has a tip on how to convince a customer because he already knew what are the customers want and needs if he /she fulfill that then for sure many gamblers will attract and get their attention to a new launch casino. And the best think to do if he gonna open an casino is that he must have enough money to sustain the casino if the players will win and also have a facilitator to maintain and control the gamblers.
