The thing is they haven't launched it, so you can't tell if it's scam or not, but I have a friend that have passed his KYC (Know your customer) and have transferred his transferable pi to his wallet,
I also have a friend that sold his pi to someone for a huge amount of money, and was still looking for more to buy, so I think if pi will be something big then that will be in years time, and not definitely this year or next year.
If the network has not launched for that long, shouldn't that be enough of a red flag to show you that this is disaster waiting to happen?
At this point, I am not sure how many people wasted their time and resources with a promise that they would become “rich” through pi network and yet today, it hasn't even launched after several months of waiting. I believe some have already cut their losses and given up
