Recently, we've been discussing what to expect from on-chain privacy, and my own conclusion is a bit "disappointing": frankly, privacy isn't about "disappearing," but more about "being less easily pulled up at random." Whether you use mixing coins/privacy layers or not, what can be blocked are casual onlookers and data companies creating bulk profiles; it's unlikely to block those with authority and resources conducting compliant investigations. This boundary will be crossed sooner or later.

In fact, the most realistic expectation for ordinary users is: don't treat privacy as a shield or a small tool to reduce exposure; keep a copy of the evidence (transfer records, source explanations) yourself. By the way, in the past few days, before and after the mainstream public chain upgrade/maintenance, people have been guessing whether projects will migrate. Anyway, I think whether they migrate or not, it doesn't matter; even if the chain changes, the compliance line won't suddenly break. Those who just want to use the chain quietly may need to learn to coexist long-term with the "default transparency."
