Btw what makes mixers illegal if i may ask, them promoting anonymity and privacy or because owners dont put a face to their businesses ??
I am not claiming to have known it all, but from what I have learned so far, no government has declared crypto mixers illegal; it's either they end up ceasing the mixer or blacklisting it for use by citizens of their country, and these things only happen if they have discovered or linked any money laundering activity to that mixer. Not because the mixers promote anonymity or the owners doesn't show their face.
An example of a former case ban is the Tornado Cash crypto mixer, whose use by the country's citizens was banned by the US Department of Treasury as a result of a $7 billion case of money laundering activity.
The Bitcoin mixer is only designed to protect user privacy and synonimity, nothing else, but due to some people that use it for illicit activity and crim to launder money, that's why the Treasury Department is against it.
Doesnt bitcoin fall in this category too as its illegal in some counties...
Bitcoin is not illegal; it is only banned in those countries.
And where does this leave coins such as Monero ?
Monero also protects users privacy, so it can only be banned in some countries that also disagree with the privacy of crypto users, just as Dubai has placed a ban on privacy coins.
