About Kevin Wu: what this site does and how the data is checked

Kevin Wu is a site that compiles crypto exchange referral codes, automatic rebates and trading fees. The numbers here come from the exchanges’ official pages and public APIs, and every article states the date its rules were checked. Rebate rates sync automatically every day, and articles are updated when the rules change. This site is not an exchange, does not hold anyone’s funds and does not give investment advice.

What does this site do?

  • Compiles the referral codes and official automatic rebate rates of more than ten major exchanges, along with their rules for adding a code after sign-up and switching referrers, all in one place: Crypto exchange referral codes.
  • Turns the official rules on trading fees, withdrawal fees, KYC, deposits and withdrawals into guides, with the original sources attached so you can check them yourself.
  • Covers hack history, proof of reserves and common scams, so you can see the risks clearly before you sign up.

What this site does not do: it does not hand out rebates, red packets or airdrops, does not charge you anything, will never message you privately asking for a transfer, and will never ask for your password or verification code. Anyone who contacts you like this in Kevin Wu’s name is an impersonator.

Where does the data come from, and how often is it updated?

  • Rebate rates: synced automatically every day from the referral code’s backend settings, not copied by hand. How the data is compiled and verified is explained in How rebate data is compiled and verified.
  • Rules and fees: taken only from the exchanges’ official help centers, fee pages, announcements and public APIs. Where the exchange does not spell something out, the article says “not stated officially” rather than filling the gap with a guess.
  • Check dates: every article opens with a “rules checked” date. When a number changes, the text is updated and given a new check date.
  • Monthly records: changes in each exchange’s rebate rate are tracked in the monthly exchange rebate rate report, and the full rules can be downloaded from the exchange referral rules dataset (CSV/JSON).
  • Sorting: how the hub’s default order and its other sort options are calculated is explained in How exchanges are ranked.

Do the rebates actually get paid?

If you sign up with a referral code from this site, the exchange pays the rebate straight to your account according to its official settings; it never passes through this site. Bybit has no automatic rebate for invitees, so the route this site points to is Fee Otter: Fee Otter pays that rebate — not the exchange and not Kevin Wu; the rate is whatever the Fee Otter page shows. Below is a screenshot of my own Fee Otter dashboard:

Kevin Wu's own Fee Otter dashboard: the Bybit account shows “Verified”, and the rebate history lists two Bybit payouts, on 2026-10-11 and 10-12. The UID and the amounts from other exchanges are masked.

To check whether your account is bound to the referral code and whether the rebates are coming in, follow the referral code check guide and what to do if your rebate has not arrived step by step.

Referral relationships and risk disclosure

The exchange articles on this site and the referral code hub contain referral links and referral codes. The content is market information and personal experience, not investment, solicitation or financial advice. Crypto prices are volatile and you could lose all of your principal; futures and leverage can wipe out your entire margin in a short time; automatic rebates only reduce what you spend on fees and cannot offset trading losses. Full details are in the referral link disclosure and risk statement.

Found an error? How to get in touch

Exchanges change their rules often, so some articles will inevitably fall behind. If a number or rule doesn’t match the official page, please let me know through the official accounts below; it helps if you include the URL of the official page you saw. Once I’ve confirmed it, I’ll update the article and give it a new check date.

Kevin Wu will only contact you through the accounts above. Anyone else who claims to be Kevin Wu and messages you asking for a transfer, an “unfreezing fee” or your account details is not this site. Common tactics are covered in Common crypto exchange scams.
