I think right now, there is some project that needs token holders to filled KYC and the participants that join in the campaign needs to fill KYC too before they can receive their tokens. maybe it will be good for the participants and the project itself so they can monitor who is the person that still give a back up for the project. but I think there are some people doesn't want to fill KYC as they think that in the cryptocurrency, we have a freedom to hide our personal information from anyone. we are free to choose what we want in the cryptocurrency and we need to know the project before we decide to join and filled the KYC.
