Yes. State licensed and regulated online casinos are perfectly safe and completely legitimate. State online gambling regulation demands it and ensures it.
Regulators vet online casinos, mandate security protocols, and test all gaming security and games for legitimacy and fairness.
Ultimately, this ensures your online gambling experience with a legal online casino is consistently a safe and legit one.
Unregulated online casinos do not bear the same assurances. Its a buyer beware market.
