What is the pros and cons of doing the KYC during the ICO or post the ICO?
I've participated in many ICOs, some of the force you to do the KYC before you can buy their tokens, others they wait and later send you a KYC email/request. so i am wondering what are the pros and cons of each approach
if I think it's a bit risky for KYC with an identity card, this is because our personal data could be used to commit a crime or other misuse
