Because scams and frauds multiply and we need some changes for us to move on and put everything into places. Now , if the site requires KYC and its a part of their regulation, if you do not want to obey them , then better find something without requiring your information. Withdrawing money absolutely needs personal information for security, what do you expect?
Right. When you are on right move with legit ICOs, then no fall back in giving them the personal documents required to verify your identity. It is indeed needed when so many fraudulent activities are easily taken upon using our personal information shared. So be more aware of giving out your personal documents to anyone. If the documents are required for the right purpose, then don't hesitate giving out them.
Are you sure that your advice is really correct? You can't determine 100% the true goals of the ICO creators. Maybe they want to take over not only your money but also your personal data. No one is immune from this threat. It seems to me that it is impossible to call any data personal now. Know two-knows pig.
