Bitcoin has become one of the most popular digital assets worldwide, and more people are looking to enter the crypto market through trusted platforms. One of the leading exchanges that enables seamless trading is OKX, known for its security, user-friendly interface, and robust C2C (peer-to-peer) functionality. This guide will walk you through everything you need to know about buying and selling Bitcoin on OKX—from currency settings and transactions to safety tips and withdrawal processes.
Whether you're a beginner or an experienced trader, understanding how to navigate OKX efficiently is key to maximizing your investment potential in 2025 and beyond.
Setting Your Preferred Currency on OKX
When you first log into OKX, the default display currency may be in USD. However, if you're based in China or prefer viewing prices in Chinese Yuan (CNY), you can easily switch this setting:
- Click the profile icon in the top-left corner.
- Tap the arrow next to your username.
- Go to Preferences > Pricing Currency.
- Change from USD to CNY.
Once updated, all asset prices—including Bitcoin—will appear in RMB, making it easier for local users to track value and make informed decisions.

Understanding Bitcoin’s Current Market Value
After switching your display currency, return to the OKX homepage. You’ll see the current price of one Bitcoin (BTC)—for example, around ¥700,000. But what if you want to sell part or all of your holdings?
The good news: Bitcoin is highly liquid, especially on major platforms like OKX. You don’t have to worry about being unable to cash out. Thanks to a large network of verified traders and automated escrow systems, converting BTC to fiat (like RMB) is fast, secure, and straightforward.
How to Sell Bitcoin via C2C Trading on OKX
OKX offers a C2C trading feature that allows users to directly sell Bitcoin or stablecoins like USDT to other users—called merchants—who pay via bank transfer, Alipay, or WeChat Pay.
Step-by-Step: Selling USDT for RMB
- From the homepage, tap [C2C Buy].
- Switch to the [Sell] tab.
- Select the cryptocurrency (e.g., USDT) and enter the amount (e.g., 1,000 USDT).
- Confirm the order — no fees apply for C2C sales.
You'll then be shown a list of available merchants. Choose one with:
- High order volume (e.g., tens of thousands of completed trades)
- High completion rate (ideally above 99%)
- Long-standing registration (e.g., active since 2022 or earlier)
For example, a merchant like “Ba Min Trading” with over 60,000 completed orders since January 2023 is considered reliable.
How Escrow Protection Works
One common concern among new users is: What if I send the coin but don’t receive payment?
Here’s why OKX’s system protects you:
- When you initiate a sale, your cryptocurrency is automatically locked in escrow by OKX.
- The buyer must send payment first via their chosen method (bank transfer, Alipay, etc.).
- Only after you confirm receipt of funds does OKX release the crypto to the buyer.
- If the buyer fails to pay, the transaction is canceled, and your funds are returned.
This "payment-first, release-later" mechanism ensures neither party can cheat.
How to Buy Bitcoin Using RMB on OKX
To invest in Bitcoin, most users follow a two-step process using USDT, a stablecoin pegged 1:1 to the US dollar.
Step 1: Buy USDT with RMB
- Tap [C2C Buy] on the homepage.
- Choose USDT as the coin.
- Enter the amount in RMB (e.g., ¥100).
- Select your preferred payment method: bank card, Alipay, or WeChat Pay.
- Click [Buy USDT].
Now browse through available sellers. Prioritize those with:
- High trade count (e.g., 100,000+ completed orders)
- Completion rate ≥ 99.9%
- Long account history (e.g., registered since mid-2022)
For instance, a seller named “Safe Little Shop,” active since June 2022 with over 100,000 successful trades, is a trustworthy option.
After selecting a seller:
- Enter the RMB amount (within their limits, e.g., ¥100–¥490).
- Click [0 Fee Purchase USDT].
- Follow instructions in chat (e.g., use same-name Alipay account).
- Complete payment and upload a screenshot as proof.
- Wait for the seller to release USDT (usually within minutes).
🔒 Always keep transaction records. If issues arise, OKX customer support can intervene using your payment evidence.

Step 2: Exchange USDT for Bitcoin
Once you own USDT, go to the trading section:
- Tap [Trade] > search for BTC/USDT.
Choose between:
- Limit Order: Set your desired price (e.g., buy BTC when it hits ¥95,000).
- Market Order: Instant purchase at current market rate.
With a market order, simply drag the slider to set your amount and tap [Buy BTC]. The transaction completes immediately.
Your purchased Bitcoin will appear in your spot wallet.
Selling Bitcoin Back to RMB: Full Withdrawal Process
When you’re ready to cash out:
- Return to the BTC/USDT trading pair.
- Tap [Sell] and select Sell All if needed.
- Confirm the trade—your BTC converts instantly to USDT.
Then:
- Go back to [C2C Buy] > switch to [Sell].
- Choose USDT, enter amount (e.g., 100 USDT), and confirm.
- Select a high-reputation buyer.
- After they send RMB to your account, verify receipt and click [Confirm Received].
- OKX releases the USDT to them.
You now have RMB in your personal bank account or e-wallet.
Frequently Asked Questions (FAQ)
Q1: Is it safe to sell Bitcoin on OKX C2C?
Yes. All trades are protected by OKX’s escrow system. Your crypto remains locked until you confirm payment receipt. Only transact with high-volume, high-rating merchants for added safety.
Q2: Are there fees for C2C trading?
No. C2C purchases and sales on OKX are completely fee-free for both buyers and sellers.
