KYC is something to do with multiple account prevention, There are some people who are greedy which prefer to use multiple accounts to earn much profits, This could be fall to cheating, Thats why KYC is very important to counterpart the issue.
I think even though I have to say that it's crazy enough number ICO according to the rules KYC by SEC. amount you think not 3000, it's $ 10.000. that's the number of financial institutions in the United States that make you fill the form to know what you do with this money, as they want to know what is going on with a large amount of money transferred to everywhere. but not, it's not the case when it comes to ICO and KYC because you buy bitcoin and not transfer a large amount of money to someone - you really buy something.
