I like the idea of posting your bankroll wallet so your members know that you have the money to pay the winners and they will see if the balance is run out of the money.
That can help convince the members that you are trying to run your business without having financial problems.
It is good to hear that you will not apply KYC for your customers and I hope you will not be implemented it in the future so we can play gambling anonymously without thinking about KYC.
If you add slot games to your site from one of the famous providers, will they ask you about licenses and other things related to KYC?
If they allow you to do that, it will be good to add more slot games since gambling games are very popular among gamblers.
