I would love to have a general conversation around mixers and if they are legal. I've heard both sides. Would be great to have someone involved in the legal side of things like Ciphertrace or a regulator to shed light on this topic
Aren't mixers in general designed to be untraceable? If you need to use it, you just go and do so.
My opinion that using mixers is more of an ETHICAL conversation instead of a legal one, because legally nobody will really be able to trace your coins or prove you used a mixer (if you use a real non-shitty/scammy one that is).
