Buying bitcoin through a dex and using Bitcoin as a decentralised digital currency as it is should be enough for everybody that wants some privacy, but as the smarter ass that you are you want something that can't be traced, the question is why?

Decentralised system enhance privacy by distribution of data and empowering the users control or even preventing unauthorised surveillance like the definition said, if you want more you are likely a criminal.

We are many on this forum and I believe that only very few people on here have a good reason why they want their transaction hidden completely but others are bad people pretending to be good until proven or caught red handed.

I can boldy call such people selfish too because, you care about yourself only and not others in the world, for your own sake you want transactions to be hidden by using means like Mixers and Co.

Let's pretend once more that you have good intent, how about drug dealers? How about smugglers? How about human traffickers? Your way is how they get away with crimes too, and you think your good intent matters?

If you are left with two options to either safe people's life like around the globe by giving up on privacy via untracable transactions or keep using the likes of mixers like you don't care which will you go for?

Until one day your sisters and brothers becomes a victim of these evil people, caring only about what you will get out of something is why the world get so evil, people don't think about the impact it will have on others, until they become victims themselves.

I would rather see every means of hiding transactions 100% vanished than battling with human traffickers in the country, if it's not happening in your country it's a huge problem in mine, Bitcoin decentralisation is enough.
