These days, the community is once again arguing over privacy coins and coin mixing.

I'm just watching and feeling a bit guilty...
Honestly, I used to think "on-chain anonymity = freedom," but the more I look, the more I realize that ordinary people’s privacy expectations are actually quite limited:
You can avoid being watched by passersby, but don’t expect to completely remove yourself from the rules.
The line of compliance isn’t written on the chain for you to see; it’s more like an air wall—only when you hit it do you realize it hurts.

My current expectation is: where a record needs to be kept, it will be kept;
if you want to use privacy tools, you should also accept being scrutinized more closely, especially if the source and destination of funds are complex, it gets very troublesome.
Anyway, I’m still into NFTs, but I care more about whether the path is clean, and I don’t want to indulge in that feeling of "looking more invisible."

What I’ve learned isn’t techniques, but that: on-chain privacy is often just about "being less disturbed," not "being immune from disturbance."
