Are you looking for a Pi invite code? If you haven't heard of Pi it is a new cryptocurrency developed by students of Stanford University in the US. While it isn't currently trading it is open for mining and the number of miners or "Pioneers" is growing by the day (10 million already). Periodically the mining rate for new users halves so it pays to get in early while you still can.
If you're interested and have downloaded the app but need an invite code please feel free to use mine.
Here's the link: https://minepi.com/Gouch
Invite code: Gouch
Update: There's now 13 million Pioneers.
