My first week of having this and it seems very simple. Essentially you need to download the App, and click 'mine' once a day. It appears to have no impact on your battery and it is free to use. You are mining coins that currently have a value of 0, but perhaps one day may be more (if this currency takes off). In all likelihood, you are unlikely to make much from this, but you never know.
You need to be referred to use it (the referrer earns a rate of 0.025pi an hour for a referral, and the person referred also earns 0.025pi an hour). The referrer doesn't earn anything from anyone the person they refer, refers.....if that makes sense. So not a complete pyramid.
In case you are interested, please feel free to use my referral code: minepi.c0m/alexhewlett
If you do your own research (which I would obviously strongly suggest you do), feel free to use an alternative referral code.
Thanks
