Poland's President has vetoed a cryptocurrency market bill for the second time, which was intended to align with the European Union's Markets in Crypto-Assets (MiCA) regulation. According to NS3.AI, this decision prevents the establishment of a national licensing system for crypto firms in Poland. With the EU-wide MiCA implementation deadline set for July 2026, the absence of a clear domestic regulatory framework is causing uncertainty among crypto businesses in the country. This situation raises concerns about compliance and market stability as firms navigate the evolving regulatory landscape.
