I recoment to take a look at this thread where bitcointalk community discussed Pi network:
https://bitcointalk.org/index.php?topic=5237735.0The conclusion was: Its a scam, It collects too much info and you are risking for close to 0:
0.25 PI per hour = 6 PI for day for 3 million nodes ... 18 million supply daily for how long? More than a year? We can estimate that it is about 18 * 10^6 * 365 / (lets say linear increment so 2) = 3 billion supply
With 3 billion supply we are talking about 1 billion dollars in marketcap (top 15 CMC). We should expect price drop 99% after unlocking tokes. For everyone considering mining (thinking that money is more important than your personal data) - you will not get even a fraction of what you think you will get. I'm wondering what is this price based on? Who is selling if all mined coins are locked? In reality this is a top 500 - 1000 CMC project currently (my estimation ... of cours if not scam) so we are talking about 2 milion marketcap and 0.0006 $ per PI, 0,004$ per DAY, 1,46$ per YEAR per NODE risking all your personal data
I would stay away from this project.
