1-their website says that the application actually mines the coin!
2-The application steals more than your info!

4-here is a Virustotal scan for their apk and it shows that the app takes a lot of permissions that steal everything on your phone https://www.virustotal.com/gui/file/3aa2994e6885d0c3fcff3b038f8b4da9b727138c5cc10533b0e8ebedb3075b41/details
