Poland has intensified its efforts to combat payments directed to the grey area of online gambling, focusing on financial institutions that facilitate the transfer of funds to unlicensed operators. Regulators are calling on payment service providers to verify their counterparties’ activities and to cease cooperation with entities listed in the register of domains infringing the law, emphasizing that failure to act may result in administrative, criminal, or fiscal-criminal liability. The discussion on this matter gained momentum during the European Financial Congress in Sopot, where the establishment of a dedicated task force to counter transfers of funds to illegal operators was proposed. Poland’s actions may serve as a catalyst for broader harmonization of regulations at the European Union level, particularly in the context of the emerging regulatory framework for the cryptocurrency market.
