Pi Network is a new cryptocurrency that was developed by a group of Stanford University Ph.D. that you can earn with your cell phone.
You can earn your own PI coins for free, just download the Pi Network app from the Google Play Store or Apple App Store, after installing just enter the code "Berssange" and log into the app once a day to prove that You are not a bot and that's it, you will earn a certain amount of currency per hour.
It doesn't drain your phone's battery, and you don't even need to leave the app open, the Pi doesn't affect your phone's performance or use your network data.
The currency is new and has no price yet, it's a good time to enter, so just sell the currency when it enters the market.
Good opportunity to get Pi for free and make a lot of profit later.
