2026 Guide: How to Register OKX (欧易) and Trade Bitcoin from Mainland China

The cryptocurrency market continues to evolve, and OKX (known as 欧易 in Chinese) remains one of the most popular exchanges for Chinese users. Whether you are completely new to digital assets or have dabbled in other platforms, this step‑by‑step guide walks you through the entire lifecycle: downloading the app, creating an account, safeguarding it against “frozen card” (冻卡) issues, accessing a 20 % fee discount, converting RMB into USDT, executing spot trades, and finally withdrawing your funds. All instructions are based on the recent tutorial video released by the 暗夜飞行 channel in early 2026.

Key Points at a Glance

1. Download the OKX app and start the registration flow
2. Secure your account and avoid frozen‑card problems
3. Activate the 20 % trading‑fee discount
4. Deposit RMB and purchase USDT
5. Perform spot trading (e.g., BTC/USDT)
6. Withdraw fiat or crypto safely

Below each bullet, we expand on the practical steps you’ll need to follow.

1. Download the OKX App and Start the Registration Flow

The video begins by reminding viewers that the official OKX client is available for both Android and iOS.

1. Visit the official download page – type https://www.okx.com into your browser and click the platform‑specific download button.
2. Install the app on your mobile device, then open it.
3. Tap “Sign Up” on the welcome screen. You can register using a mobile phone number, an email address, or a third‑party account (e.g., Google). The tutorial recommends using a mobile number tied to a Chinese carrier for smoother later verification.
4. Set a strong password and confirm it. The app will prompt you to create a 6‑digit login PIN; treat this as a second‑factor password.

Once you submit the information, OKX sends a verification code via SMS or email. Enter the code to complete the first registration step.

2. Secure Your Account and Avoid Frozen‑Card Problems

“Frozen card” (冻卡) refers to a situation where an exchange locks a user’s withdrawal capability because the linked bank card or payment method fails security checks. The video outlines three preventive measures:

1. Enable Two‑Factor Authentication (2FA) – Go to Account > Security and activate Google Authenticator or an SMS‑based 2FA.
2. Bind a verified bank card – Use a personal, name‑matched bank card rather than a corporate or third‑party card. The tutorial stresses that the card must be active, with a recent transaction record, to pass the anti‑fraud algorithms.
3. Complete the KYC (Know‑Your‑Customer) process – Upload a clear photo of your Chinese ID (or passport for non‑citizens) and a selfie. The video notes that once KYC is approved, the platform lifts most withdrawal limits and dramatically reduces the risk of a frozen card.

By following these steps, you keep your account in good standing and ensure that future deposits and withdrawals are processed without interruption.

3. Activate the 20 % Trading‑Fee Discount

OKX frequently runs promotional campaigns that reward active users with fee reductions. In the 2026 tutorial, the presenter shows how to claim a 20 % fee discount:

1. Navigate to “My Rewards” in the app’s main menu.
2. Locate the “20 % Trading‑Fee Discount” banner – it appears for users who have completed KYC and have a verified bank card attached.
3. Tap “Activate” and confirm the terms. The discount applies automatically to all spot‑trading fees for the next 30 days.

The video cautions that the promotion is time‑limited; once the discount period ends, you can re‑apply if you meet the eligibility criteria again.

4. Deposit RMB and Purchase USDT

Buying USDT with Chinese yuan (RMB) is the most straightforward way for mainland users to enter the crypto market, because USDT serves as a stable bridge to other assets. The tutorial walks through the deposit‑to‑purchase flow:

1. Open “Deposit” from the home screen and select RMB as the currency.
2. Choose a payment method – the app supports bank‑transfer (via the domestic UnionPay network) and third‑party payment services that are compliant with Chinese regulations.
3. Enter the amount you wish to deposit, then confirm the transaction. OKX displays a unique reference number that you must include in the bank transfer memo.
4. Wait for the confirmation – RMB deposits typically settle within 5‑30 minutes, depending on the bank’s processing speed.
5. Convert RMB to USDT – once the deposit appears in your OKX fiat wallet, tap “Buy”, select USDT, and input the amount of RMB you want to exchange. The platform shows the real‑time market price and any applicable fees. Confirm the trade, and the USDT will be credited to your crypto wallet instantly.

The presenter emphasizes double‑checking the bank memo to avoid mismatched transactions that could trigger a frozen‑card flag.

5. Perform Spot Trading (e.g., BTC/USDT)

With USDT in hand, you can start trading Bitcoin (BTC) or any other listed asset. The video demonstrates a basic spot‑trading workflow:

1. Go to “Markets” and locate the BTC/USDT pair.
2. Select “Spot Trading” – this opens the order‑book interface.
3. Choose an order type – the tutorial recommends starting with a limit order to control execution price.
4. Enter the quantity of BTC you wish to buy (or sell) and set your limit price.
5. Review the order details, including the 20 % fee discount that will be applied, then tap “Place Order.”
6. Monitor the order in the “Open Orders” tab. Once filled, the BTC appears in your crypto wallet.

For beginners, the video suggests keeping order sizes modest and using stop‑loss tools if you wish to manage downside risk, though it refrains from giving any investment advice.

6. Withdraw Fiat or Crypto Safely

When you’re ready to move funds out of OKX, the tutorial covers both fiat (RMB) and crypto withdrawals:

Crypto Withdrawal (e.g., BTC)

1. Navigate to “Withdraw” and select BTC.
2. Paste the destination address (e.g., your hardware wallet) and double‑check it.
3. Enter the amount and confirm. OKX will prompt you for the 2FA code before processing.

Fiat Withdrawal (RMB)

1. Open “Withdraw” and choose RMB.
2. Select the previously bound bank card as the destination.
3. Input the withdrawal amount – note that the platform may enforce a minimum limit.
4. Confirm the transaction with your 2FA code. The video mentions that RMB withdrawals usually complete within 1‑2 business days, depending on the receiving bank.

The presenter stresses that any deviation from the bound bank card (e.g., using a new card) will trigger a security review and could temporarily freeze the account.

FAQ

Q1: Why does OKX sometimes freeze a linked bank card?

A: The platform’s anti‑fraud system flags cards that lack recent transaction history, are corporate‑issued, or have mismatched personal information. Completing KYC, using a personal active card, and ensuring the bank transfer memo matches the reference number dramatically reduces this risk.

Q2: How long does the 20 % fee discount last, and can I renew it?

A: The discount is applied for a 30‑day window from activation. After it expires, you can re‑apply if you still meet the eligibility criteria (KYC‑verified, bank card bound, and no recent compliance violations).

Q3: Can I withdraw RMB directly to an overseas bank account?

A: OKX only supports RMB withdrawals to mainland Chinese bank cards that are verified under your account. For cross‑border transfers, you would first withdraw the crypto (e.g., USDT) to an external wallet and then use a separate service to convert it to fiat abroad.

By following the steps outlined above, newcomers in mainland China can set up an OKX account, protect it from common security pitfalls, enjoy a fee discount, and complete the full trading loop—from depositing RMB to buying USDT, trading Bitcoin, and withdrawing the proceeds. As always, stay informed about regulatory updates and practice diligent security hygiene when handling digital assets.
