Recent developments in the U.S. cryptocurrency market indicate a tightening of regulatory measures, leading to significant changes for users and service providers. Notably, the zkSNACKs coordinator and Wasabi Wallet have announced restrictions for U.S. residents and citizens, blocking them from using their coinjoin services. Similarly, ACINQ's Phoenix Wallet, a Bitcoin wallet designed for Lightning payments, will cease services for U.S. residents from May 3, 2024. These decisions come in the wake of extended warrantless surveillance and regulatory concerns, highlighting a growing crackdown on privacy-focused crypto services in the country.
