Could you please clarify whether CoinW requires Know Your Customer (KYC) verification for its users? I'm particularly interested in understanding the verification processes and requirements for opening an account and conducting transactions on the platform. Additionally, if KYC is mandatory, what information is typically requested during the verification process, and how does CoinW ensure the privacy and security of user data? Finally, are there any benefits or drawbacks to undergoing KYC verification with CoinW?
