The Curacao licence is a waste of time and space, it is just a money making exercise for the Curacao authorities and just a useless stamp for casino operators to show on their website claiming to have a licence to operate. The Curacao licence issuers will never bother forcing a casino to return stolen funds and will probably revoke their licence with great reluctance.

It is a pity Cloudbet have ruined their reputation over several years by withholding small amounts of BTC but they claim they will do so no matter the amount because it will stop scammers and it is a price worth paying. They made counter-claims against you and decided they will not pay you. There is no much that can be done.
