First of all, it should be noted that the KYC check is illegal for bounty hunters. So far, no team has given proper arguments about the legality of their claims. However, some ICO teams also agree that bounty hunters are not investors, and therefore should not be tested by KYC.
In addition, if there are so many frauds among ICO teams, as well as states that are not regulated by this process, it is dangerous for them to give them their confidential information.
