These days, there's been more arguing in the group about privacy coins and mixing coins—whether they count as "original sins"—and it's starting to wear me out... I usually focus on address paths, and the more I look, the more I feel: ordinary people shouldn't have overly romantic expectations about on-chain privacy. It's normal to not want your transactions to be easily linked with a quick search; but if you want to "completely disappear" and also avoid crossing any legal boundaries, honestly, that's quite difficult.

Many tools themselves aren't bad; what's bad is how and where they're used. The reality is: platforms, entry points, stablecoins—these areas will become increasingly sensitive. Someone will eventually ask where your money comes from and where it's going. My approach is pretty simple: don't put all assets into one address, split them up when possible; avoid coins from unknown sources; if you want to use privacy methods, think carefully about whether you can explain the worst-case scenario... Anyway, I prefer to be a bit more troublesome than have my account suddenly frozen one day.
