also worth mentioning that freebitco.in (their parent operator FBC B.V.) has already been warned by the Dutch regulator for offering illegal games of chance. According to a December 2024 ruling, FBC B.V. was ordered to comply with Dutch laws or block access to their citizens, or they will face a penalty of €280,000 per week, up to a maximum of €840,000.
