Just as my phone pop-up suddenly appeared with a red dot reminder saying "Certain mixing coins are being monitored," my first reaction wasn't to pick a side, but to move my hand away from the "Confirm" button... The mainnet Gas has taught me too many times, and this on-chain thing, to put it simply, is: you want privacy, but don't fantasize about "completely invisible and always safe."

Now, the community is arguing over privacy coins and mixing coins to the point of tearing apart, but both sides are quite sincere: one fears being labeled as a bad actor, the other fears being truly implicated.
My expectation is very simple: compliance is not just a slogan, privacy is not a talisman;
the less trace you leave, the better, but don’t engage in operations whose sources you can’t even explain clearly—costs are hard to calculate, and it’s easy to dig your own pit.
Anyway, I just use cheap chains, stay decentralized, and keep records where necessary, just to sleep well at night.
