Understanding OKX Deposit Methods
OKX supports multiple ways to fund your account, each with unique advantages and considerations. Below are the four primary deposit options available:
1. Deposit via Cryptocurrency (On-Chain Transfer)
This method involves transferring crypto from another wallet or exchange (e.g., Binance) directly into your OKX wallet—similar to a bank wire transfer.
Why it’s preferred:
Low transaction fees, especially when using USDT on the TRC20 network, which typically costs around 1 USDT per transfer. Transactions settle within minutes.
Key tip: Always confirm both the token type and network (chain) match between sender and receiver. Sending USDT via ERC20 to a TRC20-only address may result in permanent loss.
Step-by-Step: How to Deposit USDT via Blockchain
- Log in to OKX → Click "Assets" → Select "Deposit".
- Choose USDT as the token and select TRC20 as the network (recommended for low fees).
- Copy the generated deposit address or scan the QR code.
- Paste this address into your sending platform (like Binance or MAX Exchange), enter the amount, and confirm.
✅ Tip: Use exchanges like MAX to buy USDT with TWD first, then transfer to OKX for lower overall costs.

2. Instant Buy (Fiat-to-Crypto)
Ideal for users unfamiliar with blockchain mechanics, Instant Buy allows direct purchase of crypto using fiat currencies via credit cards or digital wallets like Apple Pay.
Pros:
- Fast and user-friendly interface
- No need to manage external transfers
Cons:
- Higher fees (typically 3–5%) due to payment processor charges
- Potential foreign transaction fees when paying in USD
How to Use Instant Buy
- Go to "Buy Crypto" → Select "Instant Buy".
- Choose USDT (or other stablecoins) and input the fiat amount (USD recommended to reduce FX spread).
- Select a third-party provider (e.g., MoonPay, Simplex)—top providers usually offer better rates.
- Enter card details, agree to terms, and complete the purchase.
While convenient, this method is best suited for small, urgent purchases rather than large-scale funding.
3. Peer-to-Peer (P2P) Trading
OKX’s C2C (Customer-to-Customer) marketplace connects buyers directly with sellers. You pay in local currency (e.g., TWD via bank transfer, LINE Pay), and receive USDT instantly.
Advantages:
- No platform trading fees
- Multiple payment methods supported
- Transparent pricing
Risks:
- Risk of fraud if dealing with unverified sellers
- Slight premium over spot market prices
Safe P2P Buying Tips
- Navigate to "Buy Crypto" → "P2P Trading".
- Filter offers by preferred payment method.
- Prioritize "Super Seller" or "Diamond Merchant" tags—these indicate KYC-verified traders with strong track records.
- Communicate via OKX chat before sending funds.
- Click “I’ve transferred” only after confirming payment.
This method balances cost-efficiency and accessibility, ideal for regular traders avoiding high card fees.
4. OTC Desk (Large Volume P2P)
Designed for high-net-worth individuals, OKX’s OTC (Over-the-Counter) desk facilitates bulk trades without affecting market prices.
Currently, OTC services on OKX are limited to CNY transactions, making them less accessible for international users.
Withdrawing Funds from OKX
Once you’ve traded successfully, withdrawing funds safely is crucial.
1. Withdraw Crypto (Off-Chain Transfer)
Transfer your crypto holdings (e.g., USDT, BTC) back to another exchange or personal wallet.
How to Withdraw USDT
- Go to "Assets" → "Withdraw".
- Select USDT and choose the appropriate network (e.g., TRC20 for low fees).
- Paste the recipient address from your target wallet/exchange.
- Enter amount and confirm withdrawal.
Ensure network compatibility—sending via ERC20 incurs higher gas fees (~3–7 USDT) compared to TRC20 (~1–2 USDT).
2. Sell Crypto via P2P
Convert your USDT or BTC directly into fiat through OKX’s P2P marketplace.
How to Sell Using P2P
- Go to "P2P Trading" → Click "Sell".
- Select a buyer offering favorable terms and payment method.
- Specify the amount of USDT to sell.
- Provide your bank details or preferred receipt method.
- Confirm receipt after the buyer transfers funds.
⚠️ Note: As a seller, you face counterparty risk—only release crypto after confirming payment.
How to Buy Bitcoin (BTC) with USDT on OKX
After depositing USDT, you’re ready to purchase BTC using two main methods:
Method 1: Swap (Instant Exchange)
The Swap feature enables quick conversions between cryptocurrencies with just a few clicks.
Steps:
- Go to "Trade" → "Swap".
- Enter the USDT amount and select BTC as the target asset.
- Review the estimated BTC output and click “Swap.”
🔄 To sell BTC: Tap the double-arrow icon to reverse the trade direction.
While fast, Swap often offers slightly worse rates than spot trading—up to 50 USDT more per BTC at times.
Method 2: Spot Trading (Basic Trading)
For better pricing and control, use Spot Trading in the BTC/USDT market.
Available order types:
- Limit Order: Set your desired price; lower fee (0.08%) if your order waits on the book (Maker).
- Market Order: Buy instantly at current market price; higher fee (0.1%) as Taker.
- Stop-Limit / Stop-Market: Trigger orders when price hits a certain level—useful for setting take-profit or stop-loss levels.
Example Strategy:
- Current BTC price: 28,000 USDT
- Set a limit buy at 27,500 USDT → Only executes if price drops.
- Add a stop-loss trigger at 26,500, placing a limit sell at 27,000 → Protects against sudden drops.
- For gains: Set take-profit at 29,500, triggering a sell order at 29,000.
Using structured orders helps maintain discipline amid market volatility.
