Pi is a new crypto currency developed by Stanford PhDs.
It's a free and easy thing to do daily. It is said that it will go online soon and be tradeable, so if you want to hop aboard, here is my link. Give it a shot if you are interested. It gives you instantly one Pi coin and helps both of us mine faster.
