Actually, kyc is a bad thing. Many people can find out your address, Name and surname. But in some countries it is forbidden to participate in the ico and therefore need a kyc.
In some countries, such as the US and China, participation in ICO projects is prohibited in the sense that citizens are prohibited from investing in these projects. That is, states are afraid that their citizens will suffer losses because of ICO's risky projects and their fraudulent teams. These states do not care whether you advertise these projects or not, participating in the generosity campaigns of ICO, because in this case you can not lose your money, because you do not invest your money in such projects. Therefore, the requirement to pass a KYC test from bounty hunters is illegal. Such requirements of these states regarding bounty hunters do not and can not be. Therefore, now many ICO teams agree that the KYC audit is conducted only against investors.
