Excerpt:
The Financial Crimes Enforcement Network (FinCEN) solicited comments from the public regarding proposed policies that endanger private Bitcoin usage in America.
FinCEN's proposed definition of "CVC mixing" aims to prevent money laundering but is so broad that it may inadvertently capture a range of legitimate financial technologies and behaviors. Services like noncustodial coinjoin transactions and layer-2 protocols, which are critical for maintaining user privacy and scaling Bitcoin, could be affected by this sweeping definition.
