Based on the experience that I have read in articles about the function of KYC, it is a principle that is applied (the Bank) to find out the identity of the customer, monitor customer transaction activities including reporting suspicious transactions and has become the bank's obligation to implement them. I think this is also a positive thing to implement in cryptocurrency, with the aim of anticipating or limiting someone who wants to commit a crime. Note: that the KYC is not misused without the knowledge of the person's identity.
