In terms of reducing scams or being minimized, yes it's a good start to see casinos being licensed.

Just think of it, are you willing to play in an online casino that doesn't show the legitimacy of your business? Yes, it might not be an assurance that they won't do some dirty work in the future but likely they won't consider doing that kind of bad stuff since the whole identity of the people running the site is exposed once they apply for a license.

Real people's feedback/review + licensed casinos = should be one of the priorities to look at before using a casino
