Never mind mixer, the average IT lawyer doesn't know about crypto and how it affects legal responsibilities/risk. I say this with all due respect, and from the admittance of an IT lawyer I engage for work over the past couple of years. They're pretty great at tech, fintech, but decentralised tech (I know only Bitcoin really qualifies) is something they're only just coming to grips with.
MiCA provides much-needed clarity but it's national law (even in the EU) that's a challenge for them.
I always say, don't let your understanding be motivated by the fear of getting caught for doing something wrong. Be motivated that your personal freedoms and fundamental rights -- including money-related -- will always be under attack.
Really? I've got a few lawyer friends working for DeFi firms (specifically with regards to IP), NDA so I can't discuss too much about them. Seems like they were quite well-versed with the Crypto scene and had quite a good understanding of how the scenarios that we've mentioned would pan out. Granted that it is quite niche, but a good lawyer with some degree of knowledge in FinTech would have a very good knowledge about your rights in this issue. Again, don't think it would be wise to engage a lawyer who doesn't have any experience with whatever you're doing with.
Interestingly, from what I understand, cases involving Bitcoin are often heavily overlapped with the traditional money laundering cases and that historically prosecutor has had a harder time to build a solid case to prove malicious intent when using mixers. Regardless, if you're not doing anything illegal, then there is no case to build for anyways.
