Casino licensing bodies have different regulations - if any - on how casino operators have to conduct their business. Some keep a tougher eye on their licensees than others, for example the European regulators. They have measures to prevent fraud and money laundering, protect player funds, responsible gaming, and fair games.
Jurisdictions outside of Europe, such as Cyprus, Costa Rica, Panama or Curacao have much less strict regulations. Players have very little protection and security. You have to put your trust into the operator. Unfortunately, there are many that are not conducting serious business, and they scam the players by not paying them winnings.
