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, a d not definitely this year or next year.
