First Im not affiliated with Pi, Pi network is currently in early stage of development phase 2 testnet you cannot build your own blockchain in a week it takes years, about your concern on asking kyc and data theft on your phone its not new anymore hundreds of app today are stealing your identity once you use your phone or pc and connecting to internet your identity is at risk anymore including your lovelife

so if you are too concern about stealing your identity dont connect to internet simple, do you think this team from Standford University with MBA, PhD degree are ruining their reputation just to build a shitty scam app? its too early to criticize a project in early phase of development if you read thoroughly the whitepaper you will understand what protocol they are proposing read gain
https://minepi.com/white-paper recently they ask members of pi pioneers in chat about ico or in app ads to sustain the development of this project and instead of using a quick and easy money ico system they decided to earn organically via in app ads and I dont see any problems here
You are not affiliated with Pi, but it seems you are very well informed about Pi, how it's work, team education level etc... I personally can't really trust you that you are not connected with Pi, so I attribute your post to shilling for Pi.
I know some of the well established and functional project which develops his own network in the first year of the stage. I also know a lot of projects that have been developing the product over the years and at the end, they develop nothing. What is the next stage after "early stage of development phase 2 testnet"? The middle stage of development phase 3 testnet?
how long does it take for "early phase of development"? 10 years? more?
