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.
Oh no, no one will leave you on your own. Being a crypto based doesn't mean you deserve full freedom, with that logic bitcoin exchanges and atc all of them must be free from centralized powers and be able to run without licenses online, backed by trustworthy from community.
OP I think poor countries will be good idea for you. Usually they are open to cryptocurrencies and investments, you get cheap rentals, cheap workers and in overall they will be cost effective for your business. You need some people who will work for your online casino and since you are looking for country to operate from (or only license?), then it's a good opportunity.
