Pi is the first cryptocurrency, developed by PhDs from Stanford University, you can mine on your cell phone. Mining is free, does not drain the battery and does not require any personal data!
Info
Pi mining app was launched on March 14, 2019, and in June, the number of active users exceeded 100,000. Pi Network is currently in beta, a very early stage of development. The currency is currently being distributed to the users and the blockchain, which will be responsible for the transactions, is being set up. At the moment Pi is worth nothing.
Pi already has over a million people worldwide and the number is constantly increasing. The project is still in its infancy and now is a good time to get started. Currently, there are 450,000+APP users in more than 100 countries.
