They are doing the same thing all the other casinos with Curacao licence is doing. The licence is not strict at all, and gives the casinos a lot of room to do what they want without consequences. Curacao licenced casinos are wild west compared to Malta casinos.
Remember to always read reviews and check the quality of the casino licence before gambling on a casino/bookmaker.
Also, it has just been two days. It is normal that casinos investigate unusual patterns. If you made normal bets and play like a regular gambler, you will most likely get your money back in the end.
I think we need to start flagging those shady countries like Curacao and others and anything that incorporates in a shady jurisdiction will be flag as a possible scam, i have a list of shady countries that allow scams to operate, this are: BVI, Seychelles, Curacao, Bermuda, Cayman Island, Comoros, Mauritius, Samoa, Vanuatu, Belize, and others.
Many shady casinos operate from Curacao, they only need 25k to buy a licence to scam.
Exchanges is cheaper, for under 1000$ they can buy a licence to scam, for example
Livecoin scam exchange incorporated in Belize, in one day you can get incorporated there for under 399$
Binance scam exchange incorporated in Malta, but operating from multiple jurisdictions, BUT with the parent company incorporated in the BVI, a country with basically no laws and a licence to scam cost under 799$
Poloniex, moved to the Seychelles, no laws, African country where millionaires buy mansions by the sea, it cost 499$ for a licence to scam.
If we see legit sites, like Coinbase, incorporated in the USA, regulated.
Coins.ph Philippines, regulated
Localbitcoin Regulated Finland
Bithumb Korea and regulated
