Danger of other apps that started copying Pi Network's success.
So, be very careful the crypto market is now being flodded with other apps and coins that are mined using your phone exactly as Pi Network. Here's the danger you should be aware of however.
Most of them might be just scams and riding the current mobile mining wave/trend, but the dangerous ones are those that you install on your phone from unverified source. Once you install such apps on your phone you expose your phone to phising and possible data breach/theft, including compromising your wallet passphrase. An app on your phone can easily use your clipboard and record what you type, copy, etc.
I WOULD NEVER INSTALL AN APP ON MY PHONE FROM UNVERIFIED SOURCE. IF IT'S NOT ON GOOGLE PLAY STORE OR APPLE APP STORE I DO NOT INSTALL IT. And eve then, i might not install it if i see other negative triggers.
