Excuse me, I'm curious about the regulations surrounding CoinW. I understand that many cryptocurrency exchanges require some form of Know Your Customer (KYC) process. Is KYC mandatory for users on CoinW? If so, could you elaborate on the specifics of what kind of information and documentation is typically required during the KYC process on your platform? Additionally, I'm interested in knowing how CoinW ensures the security and privacy of this personal information during and after the KYC process.
