Verification (KYC): How to Pass Checks and Keep Your Data Safe

When buying crypto via exchangers or exchanges, you may be asked to verify your identity or card (KYC). Here we explain why it happens, how to do it safely, and why P2P and exchangers are often easier for small amounts.

Verification at Exchangers (Card KYC)

Many exchangers ask you to show the card you pay with. This is anti-fraud: they check that the card belongs to you and is not stolen or used without the owner's consent. It protects both you and the exchanger.

How to photograph your card safely:

• You can cover the middle digits of the card number with your finger, paper, or a sticker — leave only the first and last 4 digits visible if that meets the exchanger's rules.
• Always cover the CVV on the back. No one should see it: not support, not the exchanger. Only photograph the front, or the back with the three-digit code hidden.
• Take a clear photo without glare. Often one photo of the front with a partially hidden number is enough.

Verification on Exchanges (Document KYC)

On crypto exchanges (Bybit, HTX, and other centralized platforms) you usually do full KYC: upload an ID (passport or national ID), a selfie with the document or a handwritten note, and sometimes proof of address (e.g. utility bill or bank statement).

Pitfalls: why they might reject you:

• Poor photo quality — blurry, cropped, or serial number not visible. Shoot in good light with the full document in frame.
• Data mismatch — name on the document doesn't match the account name, wrong date of birth. Enter details exactly as on the ID.
• Sanctioned regions — many exchanges don't serve certain countries for legal reasons. Check allowed jurisdictions before signing up.
• Review can take from a few hours to several days. If rejected, they usually state the reason — fix it and resubmit.

Why P2P and Exchangers Are Often Better Than Exchanges

For small amounts and quick crypto buys (e.g. for gaming or withdrawals), P2P and exchangers are often more convenient than a full exchange.

• Less bureaucracy — at an exchanger you often just enter the amount, wallet address, and pay (sometimes with simple card verification). No full KYC with passport and selfie.
• No sudden account freeze — exchanges can lock your account "pending review" or on suspicion of rule-breaking. With an exchanger you do one deal and receive crypto to your wallet; exchange restrictions don't apply afterward.
• Speed — an exchanger completes a deal in 5–10 minutes without placing a complex order or waiting for verification. Pay > receive crypto to your wallet.
