"The Blockchain Integrity Act would place a two-year moratorium to prohibit financial institutions, including cryptocurrency exchanges, virtual asset service providers (VASPs), and other registered money service businesses (MSBs), from accepting incoming funds that have been routed through a mixer, as well as prevent outgoing funds from being withdrawn directly to a known mixer address."

Never send mixed coin to an exchange, because it closes the loop. So you wouldn't do that anyways. And of course you would withdraw to a private address before sending to a coin join or mixer. So this legislation is useless gesturing, showing how incapable feds are at stopping bitcoin
