The Pi app allows you to mine Pi cryptocurrency by making diverse contributions to the network. The more you contribute, the more Pi you mine. The app is also the home for your Pi account where you can stay tuned on the network updates and interact with fellow members of the Pi community.
To start mining Pi, check in every 24 hours and hit the lightning button. Once you are mining, you can boost your hourly rate by inviting trusted friends and family to join the community. After 3 days of mining, you can boost your mining rate further by building your security circle, which contributes to the overall security of the network. There are additional ways to mine Pi through Pi lockups, app engagement, and Node operations. Please refer here for details.
