Currently, most of the exchanges (CEX) are KYC required. As we all know, most of the crypto currencies (especially bitcoin) are decentralized and anonymous.

Why should those exchanges collect our personal information? Do you think KYC is necessary?

I'm doing a research, and made a survey, so can anyone be interested in this topic share your opinion? Thanks.
