Hello, Marvin here, the developer of several apps like Minesweeper 3D, Fluids & Sounds and many more.
Today I want to use the opportunity to tell you about a new, upcoming cryptocurrency project called "Pi network" I would like to support.
It's completly free and based on the Blockchain. Currently you can sign up and get coins for free. Pi is a new digital currency developed by Stanford PhDs, with over 23 million members worldwide. To claim your Pi, follow this link Pi network and use my username (marvinkrueger) as your invitation code.
