What Exactly Is a Trading Pair
If you've just entered Binance's trading page, you may have noticed a long list of symbol combinations like "BTC/USDT," "ETH/BTC," and "BNB/USDT." These are called trading pairs.
The concept of a trading pair is actually quite simple. In everyday life, if you go to a bank to exchange CNY for USD, this exchange relationship can be written as "USD/CNY." The cryptocurrency market works the same way — each trading pair represents the exchange relationship between two assets.
Take BTC/USDT as an example. This trading pair means you use USDT to buy or sell BTC. The BTC before the slash is called the "base currency," and the USDT after the slash is called the "quote currency."
When you see the BTC/USDT price displayed as 60,000, it means the price of 1 BTC equals 60,000 USDT.
Understanding Base Currency and Quote Currency
Understanding these two concepts is very important, as they determine exactly what you're spending and what you're receiving when trading.
Base Currency (left side): This is the asset you want to buy or sell. In BTC/USDT, BTC is the base currency. When you click "Buy" in this trading pair, you're buying BTC; when you click "Sell," you're selling BTC.
Quote Currency (right side): This is the currency used to measure the price and make payments. In BTC/USDT, USDT is the quote currency. When buying BTC, you pay with USDT; when selling BTC, you receive USDT.
Here's another example: the ETH/BTC trading pair. The base currency is ETH and the quote currency is BTC. When trading this pair, you spend BTC to buy ETH, or sell ETH to receive BTC.
Common Trading Pair Categories on Binance
Trading pairs on Binance can be categorized by their quote currency (the coin on the right side):
USDT Zone: Trading pairs with USDT as the quote currency, such as BTC/USDT, ETH/USDT, and BNB/USDT. This is the most commonly used zone because USDT is a stablecoin pegged to the US dollar, making prices easy to understand.
BTC Zone: Trading pairs with BTC as the quote currency, such as ETH/BTC and BNB/BTC. In this zone, prices are denominated in BTC. This is suitable for traders who use BTC as their portfolio benchmark.
ETH Zone: Trading pairs with ETH as the quote currency. Less commonly used, mainly for direct exchanges between ETH and smaller tokens.
BNB Zone: Trading pairs with BNB as the quote currency. Suitable for BNB holders who want to swap directly for other coins.
FDUSD Zone: Trading pairs with FDUSD (another stablecoin) as the quote currency, with some pairs offering zero trading fees.
For most users, using the USDT zone is sufficient.
How to Read Trading Pair Price Information
When you open the BTC/USDT trading page, you'll see lots of numbers and information. Here are the most important ones:
Latest Price: The largest number on the page is the latest traded price of BTC, denominated in USDT.
24-Hour Change: Usually shown as a percentage with color coding. Green indicates the price has risen over the past 24 hours, while red indicates a decline.
24-Hour High/Low: The price extremes over the past 24 hours, helping you understand the recent price volatility range.
24-Hour Volume: The total traded amount or quantity for this trading pair over the past 24 hours. Higher volume indicates a more active market with better liquidity.
Best Bid/Ask Price: The current best buy and sell quotes on the order book. The gap between the best bid and best ask is called the "spread" — a smaller spread indicates better liquidity.
How to Choose the Right Trading Pair
When choosing a trading pair, consider the following factors:
What coins do you hold: If you have USDT, go to the USDT zone. If you have BTC, you can trade directly in the BTC zone.
Liquidity: The same coin may have multiple trading pairs. For example, ETH has both ETH/USDT and ETH/BTC. Generally, USDT trading pairs have the best liquidity, deepest order books, and lowest slippage.
Fees: Some trading pairs (like BTC/FDUSD) may enjoy zero-fee promotions. Keep an eye on Binance announcements for the latest fee discount events.
Trading purpose: If you ultimately want to hold BTC and currently hold ETH, trading directly on the ETH/BTC pair saves one layer of fees compared to first converting to USDT and then buying BTC.
Price Calculation Across Trading Pairs
Understanding price calculation is very helpful for evaluating trading pair value.
If BTC/USDT = 60,000 and ETH/USDT = 3,000, then the theoretical price of ETH/BTC is 3,000/60,000 = 0.05. In other words, 1 ETH is approximately equal to 0.05 BTC.
This price relationship is generally consistent across different trading pairs. If a significant deviation occurs, there may be an arbitrage opportunity — but ordinary users don't need to worry about this.
If you want to know the price of a coin in Chinese yuan, you can simply multiply the USDT trading pair price by the USDT-to-CNY exchange rate (approximately 7.1-7.3). For example, if BTC/USDT = 60,000, then 1 BTC is approximately 60,000 x 7.2 = 432,000 CNY.
How to Find Trading Pairs on the Binance App
Method 1: Search function. Enter a coin name (such as "BTC") in the search box on the trading page, and the system will display all trading pairs containing BTC.
Method 2: Zone browsing. On the spot trading page, there are tabs at the top for different trading zones (USDT, BTC, BNB, etc.). Click on a tab to view all trading pairs in that zone.
Method 3: Favorites list. You can add frequently used trading pairs to your favorites list by clicking the star icon next to the trading pair. Next time you can find them directly in your favorites.
Method 4: Markets page. On the "Markets" page of the Binance App, you can sort by price change, volume, and other dimensions to quickly find trading pairs that interest you.
Common Beginner Confusions
Question 1: Are BTC/USDT and USDT/BTC the same thing? No. BTC/USDT means buying BTC with USDT, where the price is in the tens of thousands of USDT. USDT/BTC means buying USDT with BTC, where the price is a very small number. In practice, Binance primarily offers the BTC/USDT direction.
Question 2: Why does the same coin have different prices across different trading pairs? Different trading pairs use different price units. BTC/USDT shows the price in USDT, while BTC/ETH shows the price in ETH. After converting to the same unit, the prices should be essentially the same.
Question 3: Which trading pair offers the best deal? USDT trading pairs generally have the best liquidity and are suitable for most users. If certain trading pairs have fee promotions (like zero fees), using them during the promotional period will be more cost-effective.
Question 4: Can trading pairs disappear? Yes. If a coin gets delisted from Binance, its corresponding trading pairs will also be removed. Binance will announce this in advance and give users sufficient time to manage their positions.
Understanding the concept of trading pairs is fundamental to using any cryptocurrency exchange. Once you master this concept, you'll be able to freely exchange and trade between various coins on Binance.
