Continue reading for detailed steps and cautions.
4. Key Considerations and Security Recommendations
1. Trading Safety
- Only conduct transactions through the official OKX platform to avoid phishing links and “buy‑on‑behalf” scams.
- Before committing a large amount, place a small test order to verify the seller’s reputation.
- Double‑check the beneficiary details when making a bank transfer to prevent mis‑directed payments.
- After the trade is settled, it is advisable to transfer the BTC to a personal wallet as soon as possible; hardware wallets (e.g., Ledger, Trezor) offer the highest level of security.
2. Fee Overview
| Fee Type | Rate / Description |
|---|---|
| Fiat‑to‑Crypto Purchase | Most sellers charge **0 %** (no fee) |
| Spot Trading | **0.06 %–0.08 %** for regular users; higher VIP tiers enjoy lower rates |
| Withdrawal | Miner fee determined by on‑chain network congestion; BTC withdrawal ≈ **0.0005 BTC** per transaction |
3. Risk Management
- Beginners should adopt a small‑scale trial approach, limiting any single trade to no more than 5 % of total assets.
- Set stop‑loss levels, build positions in batches, and avoid chasing price spikes blindly.
- Refrain from using high‑risk products such as margin trading or futures contracts.
- Regularly export your mnemonic phrase or private key and store an offline backup.

Step 2: Purchase USDT with Fiat
- Launch the OKX app and tap “C2C Buy” on the home screen to enter the over‑the‑counter (OTC) marketplace.

- Switch to the “Selected Area” tab at the top, then tap the “Buy” button.

- Choose the cryptocurrency USDT (Tether).

- Enter the amount of fiat you wish to spend (e.g., 500 CNY). The system will automatically display the equivalent USDT amount.

- Select a payment method – OKX supports bank cards, Alipay, WeChat Pay, and other channels.

Tip: Tick the “Beginner‑Friendly Order” option to prioritize matching with reputable merchants, thereby increasing the likelihood of a smooth transaction.

How to Choose a Merchant
- Trading Volume: Prefer merchants with a monthly volume of ≥ 50 k orders.
- Positive Rating: A rating above 99 % indicates high buyer satisfaction.
- Response Speed: Fast‑responding sellers can expedite order completion.
*Example:* A seller with 80 k monthly orders and a 99.99 % positive rating is an ideal candidate. After clicking “Buy”, confirm the amount; the platform will show the exact USDT you will receive.

Pre‑Payment Security Checklist
- Real‑Name Transfer: Use a bank or Alipay account that matches the real‑name information on your OKX profile.
- No Remarks: Do not add any extra notes in the transfer description.
- Legal Source of Funds: Ensure the money originates from a legitimate source; avoid using funds of uncertain provenance.
Once everything checks out, tap “0 Fee Purchase”. The app will display the recipient’s account details. Follow the on‑screen instructions to complete the transfer, then press “I Have Paid”.

After the merchant confirms receipt, the USDT will be credited to your Funding Wallet. The entire process typically takes 10–30 minutes, depending on the speed of the banking system.
Check Your Balance: Navigate to “Assets → Funding Wallet” to view the newly arrived USDT. If you plan to trade, transfer the funds to your Trading Account.

Step 3: Transfer USDT to the Trading Account
- On the assets page, tap the “Transfer” button.
- Choose “Funding Wallet → Trading Account”, input the amount to move, and confirm.

Step 4: Exchange USDT for BTC
- Go to the “Trade” section and select “Spot Trading.”

- In the market list, pick the BTC/USDT pair.

- Use a Market Order to execute at the best available price.
- Enter the desired BTC amount (or the equivalent USDT value) and click “Buy” to confirm the order.

- After the trade completes, tap the “Positions” tab at the bottom to see your Bitcoin holdings (the screenshot example shows roughly 0.007 BTC).
