Submit KYC is must for some ICO`s .If things getting bad What can they do to our identification documents.What will be the worst possible things to be happen to us.
I ran an ICO for my company before. We handled the KYC ourselves on our website and it was hacked by a so-called white-hat hacker. He/she showed us a screenshot with all the information of our KYC members and asked/demanded we give him a 'reward'.
If you are participating in an ICO try and make sure their KYC platform is secured, or you may risk losing your personal data (and exposing your embarrassing selfie)!
