$PI Don't harbor any illusions about PiCoin anymore; it's a scam project. The so-called nodes are all shells with no real functions. They upgrade infinitely year after year as a distraction, pretending to be a public chain. Also, KYC is a complete mess, riddled with vulnerabilities. Over seven or eight years, not a single basic feature has been able to operate normally, except for a sign-in app with extremely poor user experience, very simple, and also full of bugs. Moreover, this app was made by paying a few hundred yuan to someone. Everything is just to attract followers and harvest the naive investors.
