What Is BTC/USDT
BTC/USDT is the highest-volume trading pair on Binance. The coin before the slash (BTC) is what you are buying or selling; the coin after the slash (USDT) is the quote currency. In plain terms, it means "buying and selling BTC with USDT."
When you see a BTC/USDT price of 65,000, it means 1 BTC is currently worth 65,000 USDT.

Worked Examples
Buying
You buy BTC with 1,000 USDT at a BTC price of 65,000 USDT:
- BTC received: 1,000 / 65,000 = 0.01538 BTC
- Fee (0.1%): 0.001 USDT deducted from the trade
- Actual amount received: approximately 0.01537 BTC
Selling
One week later, BTC rises to 68,000 USDT and you sell all 0.01537 BTC:
- Gross proceeds: 0.01537 x 68,000 = 1,045.16 USDT
- Fee (0.1%): 1.045 USDT
- Net proceeds: approximately 1,044.12 USDT
- Profit: 1,044.12 - 1,000 = 44.12 USDT (about 4.4% return)
Understanding the Trading Interface
Candlestick Chart
The top half of the trading page displays a candlestick (K-line) chart showing BTC's price history. Each candle represents the open, close, high, and low prices for a time period:
- Green candle: Price went up during that period (close > open)
- Red candle: Price went down during that period (close < open)
As a beginner, you do not need to master technical analysis of candlestick charts. Just know that it shows price movement over time.
Order Book
The middle section displays the order book (Depth/Order Book), showing all pending orders:
- Red area: Sell orders (asks, sorted from lowest to highest price)
- Green area: Buy orders (bids, sorted from highest to lowest price)
The number in the middle is the current last traded price.
Recent Trades
The right side or bottom of the page shows a live feed of recent trades, including fill price, quantity, and time for each.
FAQ
Where can I see my BTC after buying? Wallet → Spot → BTC. You can view your quantity, current value, average cost, and profit/loss.
Why is my BTC amount slightly less than expected? Because the fee is deducted from the BTC you receive. For example, you should receive 0.01538 BTC, but after the 0.1% fee, you actually get about 0.01537 BTC.
Can I buy a fraction of a BTC? Yes. BTC can be divided down to 8 decimal places. You can buy 0.001 BTC, 0.0001 BTC, or even less. The minimum order size is about 10 USDT.
Can I sell immediately after buying? Yes, spot trading has no holding period requirement. However, frequent buying and selling generates fees. If the price has not changed much in the short term, trading back and forth only generates commissions.
Are there trading hours? No. The crypto market operates 24/7, including weekends and holidays.
Can I lose everything if BTC drops? Not with spot trading. Even if BTC drops 50%, you still hold your BTC — it is just temporarily worth less. You only "realize" a loss when you sell. If you hold and the price recovers, your portfolio value recovers too. This is different from futures trading, where liquidation can wipe out your entire margin.
