They are supposedly trading at a high price at $43.20 in exchanges like HTX.
This is huobi right? It's not the actual PI that OP has mentioned but it's like a pi that made by huobi themselves to ride the hype of it but it's only tradable there, no deposits and withdrawal.
A few years back, I also participated in mining of PI coins, when its app was launched on mobile and managed to accumulate few hundereds of PI coins, later the team also introduced very challenging KYC process, it became apparent to me resized that the team might not be fully committed to ensure the success of the project not serious to make it a success. As a result, I stopped mining and ceased my involvement with the project, including keeping up with its updates.
Good thing that you've come to realize that. I still see a lot of people that can't accept that they've spent a lot of time on it doing all of the required process and requirements and then, there's no progress at all anymore. That's why if these people will just realize that they can use their time from committing into this project, they'd be better doing it with some other projects that are legitimate and tradable into exchanges unlike this one, you should be done with all of it.
