KYC The bounty hunter
#. can at least reduce cheating or multi-accounts.
The KYC team & developers
#. can at least reduce a few% of the number of fraud projects, this symbolizes a good project if their team is solid, transparent and responsible.
KYC is over, many people don't trust KYC because there are many cases of misuse and sale of personal data. I've even seen some ICO projects use other people's data and they put it as one of the development teams. somehow they can get it for sure it all started from too easily people give their personal data.
so we can't guarantee whether the project is quality or not, because it's too easy to fake.
