Many online casinos get registered in Curacao, Malta, Cyprus.
Casinos that aren't licensed are not worse than those with a license. Licenses cost you money so you need a decent turnover to be able to afford it. Many operators don't apply especuially when the business is in aa early stage.
Lol, wtf you're telling to others. Without license your domen name can be blocked anytime (because of that many bitcoin casinos have black list of countries, like USA, because if they will accept people from USA without license, they will be seized) if any customer will complain to goverment. The best way is to buy offshore license (like Baham island or Cyprus) because this countries have agreement with UK and EU about gambling policy.
You can start your business without license, but be ready to stay in darkness forever.
