If you're new to cryptocurrency, terms like USDT can be confusing. How does it differ from USD? Why do exchanges use it? This guide explains everything in simple terms.
Understanding USDT (Tether)
USDT, commonly called "Tether," is a stablecoin created by Tether Limited. Unlike volatile cryptocurrencies, it's pegged 1:1 to the US dollar (USD), meaning:
- Each USDT is backed by $1 in reserves
- It maintains ~98% price stability
- Serves as a bridge between fiat currencies and crypto

How USDT Works in Crypto Trading
1. Buying Crypto with USDT
Exchanges don't directly accept fiat currencies for crypto purchases. The standard process:
- Deposit local currency (e.g., CNY)
- Convert to USDT
- Use USDT to buy BTC/ETH/etc.
2. Price Fluctuations
While relatively stable, USDT varies slightly (±3-5%) due to:
- USD exchange rate changes
- Market demand (more buyers → higher USDT price)
Strategic USDT Usage
Smart traders leverage USDT by:
- Buying low: Accumulate USDT during market dips
- Trading: Purchase undervalued altcoins
- Selling high: Convert back to USDT during peaks
- Cashing out: Exchange USDT for fiat when rates favor
This avoids common pitfalls like:
- Buying crypto/USDT at price peaks
- Panic-selling during corrections
