KYC for big investors is already required in every project, even small investors are required to verify KYC but not as complex as big investors, and KYC for bounty is to avoid multiple account fraud
I agree that it would be most optimal for KYC to be checked in ICO projects by those investors who buy large quantities of new tokens. Bounty hunters should not be tested by KYC at all. It is used to prevent the laundering of dirty money. Bounty hunters do not invest in ICO projects and therefore should not pass such a test.
Passing a KYC check should not be applied to bounty hunters, ostensibly to avoid multiple accounts. No state requires this, and the initiative of the ICO team in this regard is the excess of their powers. It is possible to violate our right to the confidentiality of a person only in cases provided by law, and not to whom it pleases even under the guise of the most noble cause.
If the ICO team, requiring a KYC check at the end of the ICO, would be registered in my country, I would sue for moral damage and would win the case. I speak as a lawyer who practices on similar issues.
