Step 2: Deposit Funds into Your OKX Account

You can fund your account using fiat currency or existing cryptocurrencies.

Deposit Fiat Money (Convert Local Currency to USDT)

1. Tap "Buy Crypto" on the homepage.
2. Select "Quick Buy" and choose BTC, ETH, or USDT.
3. Pick a payment method: bank transfer, Alipay, WeChat Pay.
4. Enter the amount and confirm—the system will match you with a seller.

⚠️ First-time users may be asked to upload proof of payment (e.g., bank transfer screenshot).

Deposit Cryptocurrency

To transfer crypto from an external wallet:

• Navigate to Assets → Deposit.
• Choose the cryptocurrency (e.g., BTC, ETH).
• Copy the provided deposit address.
• From your external wallet, send funds to this address.

🔒 Crucial: Always double-check the network (e.g., ERC-20, TRC-20). Mismatched networks can result in permanent fund loss.

Transfer Funds to Trading Account

For spot trading:

• Go to Assets → Funds Transfer.
• Move USDT or other coins from your Funding Account to your Trading Account.

Step 3: Buy Cryptocurrency

There are two primary ways to buy crypto on OKX: quick buy for beginners and spot trading for more control.

Method 1: Quick Buy (Ideal for Beginners)

This option allows instant purchases using local currency:

2. Search for the coin (e.g., Bitcoin).
3. Enter the amount in fiat or crypto.
4. Select your preferred payment method.
5. Confirm the order and complete payment.
6. The seller releases the crypto automatically upon confirmation.

This method is fast, simple, and perfect for first-time buyers.

Method 2: Spot Trading (Limit & Market Orders)

For greater control over price and timing:

1. Go to Trade → Spot Trading.
2. Select a trading pair (e.g., BTC/USDT).

3. Choose order type:

   • Limit Order: Set your desired price and quantity. The trade executes only when market price matches.
   • Market Order: Buy immediately at the best available price.
4. Monitor open orders under "Open Orders"—you can cancel unexecuted trades anytime.

👉 Start trading with precision using advanced order types and real-time market data.

Step 4: Sell Cryptocurrency

Selling works similarly to buying, with options for converting crypto back to fiat or swapping between digital assets.

Method 1: Quick Sell (Convert Crypto to Fiat)

To cash out:

1. Tap "Sell Crypto" → "Quick Sell".
2. Choose USDT or another stablecoin.
3. Enter the amount and select a buyer.
4. Provide your bank account, Alipay, or WeChat Pay details.
5. Once payment is confirmed in your account, release the crypto.

⚠️ Always verify that funds have arrived in your bank account before clicking “Release Crypto.”

Method 2: Exchange Crypto via Spot Trading

To swap one cryptocurrency for another:

1. Go to Trade → Spot.
2. Select a trading pair (e.g., USDT/BTC).
3. Place a sell limit order at your target price or use market sell for instant execution.
4. Proceeds go directly to your trading account—ready for reinvestment or withdrawal.
