The European Union's new cryptocurrency regulations, known as MiCA, are about to take full effect, raising questions about Tether's USDt stablecoin. While Coinbase has already delisted USDt, other exchanges in the EU, like Binance and Crypto.com, continue trading it, awaiting regulatory clarity. EU regulators haven't explicitly labeled USDt as non-compliant, but uncertainty remains. As MiCA's full implementation looms on Dec. 30, exchanges face decisions on USDt's future. A transitional phase allows some flexibility until July 2026, but the path forward is still unclear.
