Currently, the Pi Network project is in phase 2 (testnet), which is why the token cannot yet be traded and therefore has no value. Pi is technically based on the Stellar protocol with which cryptocurrencies, or digital money in general, can be stored and sent.
When the project reaches phase 3 (Mainnet), Pi will be listed on the well-known crypto exchanges. The currently early mined Pi tokens can then be turned into "real" money.
To participate, you need a Pi Network invite code or Pi Network referral code: Feel free to use "piny24" to support my work and the project.
Because in the Pi Network App with each "Halving" naturally less Pi Tokens can be generated, it is of course useful to be there as early as possible.
