Not about Curacao - but this is a quote directly from the Costa Rican authority for any casinos you have been on with a licence there. Any EOD SRL etc are on this list.
"One disadvantage of a Costa Rica gaming license is that, due to the lack of a legitimate license, you will not be able to accept payments from standard merchants and payment providers like Visa and MasterCard. Alternatively, you may accept cryptocurrency payments first and then add fiat money if you choose to seek a license in another country down the road."
So each payment is not only fraudulent transaction masking, but actually against the licence terms. Probably doesn't matter to these sites, wild west licence, but even then they cowboys have officially stated that they can't accept VISA or Mastercard there!
