I do not understand this licensing thing.
A crypto based online casino or sportsbook should be free from licensing and all those centralized powers. We already have a community and it can starts from here. I have seen several gambling sites without a real license but established now. As long as you are providing good service and abide by community commonsense then a crypto based gambling site should be fine.

However as DS said, you can talk to some local lawyers or with any law firm online who has good reputation but never listen to user game-protect in here.
