Breaking through limitations requires solid foundational skills, and this is beyond doubt. Recently, I have been following some Privacy Coin projects and found that some are indeed different. For example, one Privacy Coin sets privacy protection as the default configuration instead of an optional feature. More importantly, it has real ecological applications for support and does not rely on flashy marketing to build hype. This low-key and pragmatic approach may seem ordinary and uninteresting to those pursuing conceptual speculation, but it precisely demonstrates the project's intrinsic strength.
