Lately I've been looking into on-chain privacy-related topics, and the more I read, the more I think ordinary users shouldn't have too high expectations: on-chain is inherently a "traceable public ledger," and privacy tools at best help you obscure the path; they don't make you invisible once activated. Compliance is also a very practical concern—when it comes to risk control or investigations, exchanges, nodes, and front-end interfaces will still cooperate. In plain terms, there's always a tug-of-war between privacy, usability, and compliance.

Recently, the stacking and sharing of security yields have been criticized as "nested," and I can understand why. The more complex it gets, the more the flow of funds and responsibility boundaries are exposed first... I'm just someone slowly collecting shells. My expectation is: don't do things that shouldn't be seen, don't rely on tools to cover your tracks, and try to leave as few traces as possible. The rest is up to time and patience.
