Indeed, Bitcoin mixing is not money laundering per se, but why would anyone need to use a mixer? The most correct answer is to avoid getting tracked, by whom? Not all Bitcoin mixer users are money launderers but other motives behind using Bitcoin mixer is 80% illegal, criminal-minded, call it whatever you want, since the day I have started investing money in crypto I have never for once think of a mixer, I like the feature of a mixer but most users are into illegal things.

People who don't use mixers illegally are those who believe in privacy, which they believe is the only way to really evade the government and the watchers. Perhaps someday, a more secure mixer can be developed where people can stay off the radar of the government by using one.

For now, I don't see any reason to start using a Bitcoin mixer but I am a supporter, the ability that a mixer possess is more useful for criminals than a normal average Joe, that's my point.
