Well as a minimum standard many gaming websites show they have some sort of incorporation use Curaçao Licence.

In essence, if companies are incorporated in their country of residence they will probably be breaking the law as they will need a casino licence which will probably never be granted to a small company or start-up. Getting a gaming licence from the UK, EU or US for a small company or start-up with small amounts of funding will never happen. Registering a casino in Costa Rica such as when serial scammer Dean Nolan did with betking.io during the ICO in 2017 using an off-shore registrar is easy. So is registering in Curaçao. Neither offer investors or game players any real protection.

One of the main things it does for the owners when using Costa Rica and Curaçao is that they remain anonymous, their names and addresses are not made public and are not accessible by anybody. In the EU you can go online and find background information on any incorporation including names and addresses of shareholders.

A Curaçao licence does not actually provide any benefit to the end user, this quote in the link below just about sums it up "The greatest disadvantage of a license from Curacao is that it doesn't have much meaning":

When Bustabit and Bustadice had an issues where some Bitcoin were stolen their owner ensured it was fixed fast and topped up the losses from his own pocket so bankroll investors did not lose out. That sort of behaviour has given Bustabit and Bustadice a great reputation and that reputation of the websites and its owner are a far bigger seal approval than the Curaçao seal.
