Pi network is planning for a big scam. To be able to withdraw and use your Pi, you will have to do full KYC. Do you know that? They have millions of users worldwide and you can imagine the kind of user data they will have once they start this process.

The only other currency I know is Phoneum which has recently changed their name to Fone. The app can be downloaded from Android store. But I can't guarantee any positive outcome from it.
