Pi is already launched and I don't really know if you have done the KYC or not but I doubt it anyone can still do the KYC.
Oi KYC was available for miners many years again which many took advantage of and many could not take it very seriously.
I don't really know why some peesons why doing something very late although it might look like he got the information at the late time or he's a new miner. Anyhow it goes, Pi has launched and many miners has made some good profits from the project.
