Pi network is a crypto currency, based in the Stellar blockchain, and developed by stanford professors.
Research Stellar. The perfect chain for mobile.
Pi is mined the same was as Electeoneum. You log on once a day, reinstigate mining, and are rewarded premined Pi/hr.
You can also download a node for computer to strengthen the chain.
Pi is not traded publically, but has plans to implement Mainnet sometime this year. Phase 3.
Some speculate that Pi is a scam, but those claims can be debunked by research.
There are no in app purchases. The only info asked for is name and mobile number, I really haven't seen any ads except for the beta browser, and you do not get rewarded for your invited member's invited members, not a pyramid.
The earlier you get in the more Pi per hour.
Pi is invite only so if you want earn free crypto with no risk go to google play, download Pi Network, and use invite code: LittleBearHero to start mining today and get +25%.
Thanks.
