KYC (Know Your Customer) is an essential process for cryptocurrency exchanges to verify user identities, aiming to prevent money laundering and illegal activities. Although many view it as an invasion of privacy, KYC can protect user assets, enhance account security, and unlock more trading features. Completing different levels of KYC can increase withdrawal limits, and users should ensure that the submitted documents meet the requirements to avoid verification failures. Through KYC, users can enjoy greater security and flexibility within the crypto ecosystem.
