How to Buy and Sell Bitcoin on OKX Exchange – A Complete Guide

·

Cryptocurrency trading has become increasingly accessible, and platforms like OKX make it simple for both beginners and experienced users to buy and sell digital assets like Bitcoin (BTC) securely. In this guide, we’ll walk you through the full process of converting fiat currency (CNY) into Bitcoin, managing trades, and cashing out—step by step.

Whether you're new to crypto or looking to refine your strategy, this tutorial ensures a smooth, secure experience on one of the world’s top exchanges.

Changing Your Display Currency to CNY

When starting on OKX, you may notice prices displayed in USD. To switch to Chinese Yuan (CNY), simply click the profile icon in the top-left corner, then select the arrow next to your username. Navigate to Preferences > Pricing Currency, and choose CNY. This adjustment helps you better track Bitcoin's value in your local currency.

Now, when you return to the homepage, you'll see Bitcoin’s current price—around 700,000 CNY per BTC—displayed clearly in RMB.

Selling Bitcoin via C2C Trading

One of the safest ways to convert Bitcoin into cash is through C2C (peer-to-peer) trading on OKX. Here’s how:

  1. Click on [C2C Buy] on the homepage.
  2. Switch to the [Sell] tab.
  3. Select the cryptocurrency you want to sell—in this case, USDT (Tether).
  4. Enter the amount (e.g., 1,000 USDT), then click [Confirm].

There are no trading fees for selling via C2C. After placing your order, choose a reputable merchant with a high completion rate and long-standing registration. For example, a seller like “Bamin Trading” with over 60,000 completed orders since January 2023 is a trustworthy option.

How C2C Protects You

OKX uses an escrow system to ensure security:

This "payment first, then release crypto" model prevents fraud. Even if a buyer fails to pay, your funds remain safe under OKX's control.

Buying USDT with Fiat Currency

Before purchasing Bitcoin, it's often more cost-effective to first buy a stablecoin like USDT, which maintains a 1:1 value with the US dollar.

Here’s how:

  1. Go to [C2C Buy].
  2. Choose USDT as the coin.
  3. Enter your desired amount (e.g., 100 CNY).
  4. Select your preferred payment method: bank card, Alipay, or WeChat Pay.
  5. Confirm your selection.

Now browse available sellers. Prioritize those with:

For instance, a merchant like “Safe Little Shop,” registered since June 2022 with over 100,000 completed trades, offers strong reliability.

Click [Buy USDT], enter the amount (within their limit—e.g., 100–490 CNY), and proceed with [0 Fee Purchase].

You’ll be prompted to review security tips—important given rising scam risks—then directed to chat with the seller.

Follow Seller Instructions Carefully

Each merchant sets specific rules. One might require:

"Only accept transfers from the same-name account used for registration."

Adhering to these conditions prevents delays. After paying via your chosen method:

The seller must now release your USDT. If they don’t, contact OKX customer support with your proof of payment—they’ll intervene fairly.

Using USDT to Buy Bitcoin

With USDT in your wallet, you're ready to invest in Bitcoin.

  1. Return to the OKX homepage.
  2. Search for BTC/USDT trading pair.
  3. Tap [Trade] to enter the exchange interface.

You’ll see several order types:

Limit Order: Buy at Your Ideal Price

Use a limit order if you want to set a specific price. For example:

Enter your desired price and quantity, then click [Buy BTC]. The trade executes only when the market reaches your set price. Until then, it appears under [Open Orders]—you can cancel it anytime via [Cancel].

Market Order: Instant Purchase

Prefer speed? Use a market order:

Your purchase completes instantly at the best available rate.

Cashing Out: From Bitcoin Back to CNY

When it’s time to withdraw profits:

  1. Go back to the BTC/USDT trading page.
  2. Click [Sell].
  3. Max out the amount and confirm [Sell BTC].

Your Bitcoin converts back into USDT.

Next:

  1. Return to the homepage.
  2. Open [C2C Buy].
  3. Tap [Sell].
  4. Choose USDT, enter the amount (e.g., 100 USDT), and confirm.

Select a reliable buyer with strong metrics and complete the transaction as before—receive CNY first, then release USDT from escrow.

Why This Strategy Is Most Efficient

The optimal path for buying and selling crypto on OKX follows this logic:

CNY → USDT → BTC → USDT → CNY

Using USDT as an intermediary minimizes slippage and reduces transaction costs compared to direct fiat-to-BTC trades.

This method applies universally:
