It was just exploited by illegal personnel in the country. They use the banner of pi to deceive in various ways. I have seen them use fake apps to scam people and then blame it on pi.

Personal Insights on Whether Pi Network is a Ponzi Scheme
We are all ordinary people, deeply engaged in the cryptocurrency world for the sake of earning a living. There are millions of pioneers of Pi Coin, and the attention it receives is so high that, looking at the cryptocurrency market, very few projects have such a large audience focused on a single coin. So, aside from the technology, let's discuss this. I see certain value in it. Even if it’s a copycat coin or a Ponzi scheme, its price is definitely established. However, it won't be like brainwashing, with prices soaring to hundreds, thousands, or even tens of thousands. If it opens at 10, that would be a blessing. If the community stabilizes later and the ecosystem develops, a slow and steady growth will occur. So, there’s no need for arguing; regardless of whether it’s a black cat or a white cat, a good cat is one that catches mice. Congratulations to those who have worked quietly; whether it's 1 yuan or 10 yuan, let’s not speculate, but rather let things unfold naturally and enjoy the fruits of your labor over these years.
