Using mixer will be expensive because the current regulations is full of KYC, so it's not gonna be easy to stay anonymous.
You need KYC to use mixer?
I don't think so. The purpose of a mixer is to protect your privacy and identity or to make anonymous transaction. Now, if mixers required KYC on their customers then it's useless. If so, it is better to use directly on Centralized Exchanges than to waste your time and effort on mixers. Technically speaking, mixers wouldn't do that if they want to take care of their customers.
If ever all the mixers required KYC in the future then decentralized exchanges would be a good alternative.
I agree that this kind of thinking can be understood given the existing problems and it all comes back to the user. If it is used for bad purposes then it will be a crime, but if it is used for good purposes then as long as it is still positive it is legal, because you just want to avoid doing it. KYC I know that every exchange definitely requires a KYC process to make money transfers, the existence of Mixer is actually a little helpful for people who don't have identity or have lost their residence card and that is identical to the KYC process, so the existence of Mixer aims to help people who lost their identity, actually it was only individuals who did this and in the end a lot of speculation emerged..
This is just speculation, my thoughts are true or not, I don't know even if I use the ad..
