I have seen evidence of some scams being run under the guise of KYC in order to gain your passport and government issued id's. Be careful out there and remember that a lot of these coins end up being scams. Do you really want them having your passport/photo identification? This is how people fall victim of identity fraud so please think before sending your information in.
Sincerely, this has been one of the things I wonder about, because many projects today are here with the motive of scamming people of their had earned money at the same time use their information to scam more people, or even sell them to third parties. God help us.
