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.
