I don't support game-protect.com,  but what I agree with them is that Curacao "license" is just a piece of toilet paper. It doesn't guarantee anything to the players as Curacao jurisdiction does not participate as a mediator in disputes between gamblers and operators. This piece of paper is not accepted by developed countries. Some casinos use it because they want to pretend that they are legit and the cheapest way to do that is to buy the Curacao "license".
