CoinW Guide

A step-by-step guide from signup to Coperral linking.

1. Start with a new account

   1 / 4

   Payback activates only when you sign up with the Coperral code. Follow the steps below.

   1. 1
      Tap 'Sign up' on the Coperral CoinW page. The referral code is applied automatically.
   2. 2
      Create an account with your email or phone number.
   3. 3
      Set a password and two-factor authentication (2FA).
   4. 4
      After signing up, check that the Coperral code appears in your referral details.
   Sign up with email or phone number + password; basic use (deposits/trading/some withdrawals) works without KYC. Caution: the US, UK, and Japan are blocked (bypassing with a VPN risks account suspension), and Korea appears on some restricted-country lists, but sources are inconsistent - confirm availability at the actual time of signup. Official Korean UI support may also change, so verify separately.

2. Complete KYC

   2 / 4

   Whether KYC is required, and the limits, vary by exchange. Check the steps and the exchange-specific note below.

   1. 1
      Prepare a government ID (passport or driver's license).
   2. 2
      In the CoinW app/web, go to Account > Verification (KYC).
   3. 3
      Follow the prompts to capture and submit your ID and a facial verification.
   4. 4
      Approval usually takes anywhere from a few minutes to a few hours.
   No - trading and withdrawals work even unverified (unverified daily withdrawal about 2 BTC). Verification has 4 tiers (Unverified / C1 basic / C2 primary / C3 advanced): C1 (nationality/name/date of birth/ID info + ID photo) raises the daily withdrawal limit; C2 raises it further (some products/services require C2 or higher); C3 (advanced) has a 100 BTC daily limit and can only be completed in the CoinW mobile app (includes facial verification). Real-name verification is limited to ages 16-75, only IDs valid for at least 3 more months are accepted, and limits reset every 24 hours. (Figures/requirements may change with policy.)

3. Check and link your UID

   3 / 4

   Register your exchange UID with Coperral to start earning payback.

   • App: Open the CoinW app, tap the account (profile) icon at the top left of the home screen, and enter the Personal Center; your UID is shown at the top of the screen.
   • Web: Log in to coinw.com and hover over (or click) the profile icon at the top right; your UID is at the top of the expanded menu.
   • The UID is a numeric unique member number. Long-press it or use the copy icon next to it, and use it for payback registration. (Menu names/icon positions may vary by app version.)

   Found your UID? One last step: register it under My account on Coperral, and payback starts accruing once verification completes.Link UID

4. Check if your existing account qualifies

   4 / 4

   Most exchanges do not allow changing the referrer on an existing account. The exceptions and alternatives are laid out below.

   • Bottom line: if you already have a CoinW account (whether the referrer is empty or set to another code), transferring to the Coperral code is impossible in principle. A referrer can only be entered at signup, and CoinW does not officially offer post-signup changes or retroactive application.
   • Recommended: create a new account with a new email/phone and enter the Coperral referrer/invite code at the signup step. (Only one UID per exchange can be linked for payback, so link the new account.)
   • If unsure, ask CoinW support (in-app/web chat or help center) directly whether the referrer can be changed. The usual answer is no.
   • Travel Rule: referrer transfer itself has no direct Korea Travel Rule issue. However, sending 1M KRW or more from a Korean exchange (Upbit, Bithumb, etc.) to CoinW is subject to the Travel Rule, so a withdrawal-exchange selection/address-registration step may be needed.
   If you switch by creating a new account, moving assets via a Korean exchange may involve extra steps under the Travel Rule, such as identity verification.
   CoinW allows one KYC per person. If you already have a verified account, the same ID cannot verify a new one.

This guide is based on each exchange's official help center and public materials, but exchange app/web UIs and policies change frequently. If menu names or locations differ, follow the exchange's customer support or the latest in-app screens.
