KYC is a standard practice borrowed from traditional finance. When you sign up to a regulated crypto exchange, it typically asks you to verify your identity by submitting a government ID and sometimes a photo or proof of address. The goal, mandated by anti-money-laundering rules in many countries, is to prevent fraud, money laundering and other illicit use by tying accounts to real people.
This is where a genuine tension in crypto shows up. Crypto grew partly around the ideals of privacy and permissionless access, and KYC runs against that grain by attaching your legal identity to your activity on a platform. Centralised exchanges generally require it; decentralised exchanges, where you trade from your own wallet, usually do not, which is one of their appeals and one of their risks.
For most everyday users, completing KYC on a reputable exchange is a normal and expected step, and often a sign the platform is operating within the rules. It is worth being mindful of the privacy trade-off and of where your documents are stored, and cautious of any unregulated platform asking for sensitive identity data. Crypto House explains KYC neutrally as part of how the regulated on-ramps work. Completing it on a reputable, regulated platform is a routine step, and is often itself a sign that the platform is operating within the rules.

KYC — perguntas frequentes
Why do exchanges require KYC?
Because anti-money-laundering regulations in many countries require regulated platforms to verify who their customers are. KYC ties accounts to real identities to help prevent fraud, money laundering and other illicit activity.
Can I use crypto without KYC?
Sometimes. Decentralised exchanges let you trade from your own wallet without identity checks. But that comes with fewer protections and more scam exposure, and regulated on-ramps from ordinary money to crypto almost always require KYC.
