Pi Network is a cryptocurrency that you can earn directly from your phone. Simply install the "Pi Network" app, register with the code Berssange and access the app once a day to prove that you are not a robot. By doing this, you will accumulate Pi for every hour of use, without the app consuming resources or affecting the performance of your phone. The currency is still new and has just been listed, but this is a great time to start accumulating. In the future, you will be able to sell your coins. A great opportunity to get Pi for free and profit a lot later.
