To be fair here, a lot of nonsense FUD is circulating about that law. It's not "banning mining" as often said because it is still possible to do mining there from existing mining farms. It's even possible to start new mining farms. But new mining farms are required to avoid reactivating old and dirty coal plants because it's targeting such cases, where old coal plants have been activated to engange in Bitcoin mining. Existing contracts will only be renewed, expanded or new miners allowed to start operation if energy used for operations is 100% renewable.
So, still valid contracts and renewable mining isn't affected as far as I know.

Regarding the debate on mixers: I haven't done any academic research on the issue but wouldn't it be 100% stupid for this hacker to use ChipMixer and think he'll go unnoticed? His big amounts sent through ChipMixer should clearly create a trackable pattern, where Chainalysis could analyze his transaction flows. Chips going out of ChipMixer have a certain "size", so trying to cash it out (and therefore consolidating his Chips) should result in a nice, trackable pattern.
So yes, let the hacker feel safe when he's trying to cash out his Bitcoin after ChipMixer while Chainalysis is well aware where he's cashing it out. Catch him, done.
= Play stupid games (use Bitcoin for criminal activity), win stupid prices (get caught).

Most criminals are underestimating how trackable a public Blockchain really is and therefore, I don't see any necessary actions against ChipMixer.
