When trading on Binance, you'll encounter several stablecoins — USDT, USDC, FDUSD. They're all pegged to $1, but they're not exactly the same. Which one should you use? What are the differences?
Basic Information on the Three Stablecoins
After registering on Binance, you'll see these three stablecoins everywhere. Here's their background:
USDT (Tether)
- Issuer: Tether
- Market cap: Largest stablecoin, circulation exceeding $100 billion
- Peg mechanism: Claimed to be backed by USD and equivalent asset reserves
- History: Launched in 2014, the oldest stablecoin
USDC
- Issuer: Circle (in partnership with Coinbase)
- Market cap: Second-largest stablecoin
- Peg mechanism: Backed by USD cash and short-term US Treasuries
- Notable feature: Regular audits, higher transparency
FDUSD (First Digital USD)
- Issuer: First Digital Labs (Hong Kong)
- Market cap: Relatively smaller
- Peg mechanism: Backed by USD and equivalent asset reserves
- Notable feature: Actively promoted by Binance
Key Differences on Binance
Number of Trading Pairs
USDT has the most trading pairs — nearly every coin has a USDT pair. USDC and FDUSD have fewer pairs, but major coins are covered.
Fee Differences
This is the most important factor when choosing:
- FDUSD pairs: Binance offers zero-fee promotions on some FDUSD pairs
- USDC pairs: Some pairs also have fee discounts
- USDT pairs: Standard rates, no special discounts
For high-volume traders, fee differences alone can save significant amounts.
C2C Liquidity
USDT has the best C2C market liquidity — the most merchants, easiest to buy and sell. USDC and FDUSD have fewer C2C merchants, and prices may be less competitive.
Withdrawal Networks
The three stablecoins support different withdrawal networks:
- USDT: Supports the most networks (ERC-20, TRC-20, BEP-20, etc.)
- USDC: Supports major networks (ERC-20, SOL, etc.)
- FDUSD: More limited network options
Practical Recommendations
Daily buying/selling and deposits/withdrawals: Use USDT. Best liquidity, most convenient C2C, globally accepted.
Large spot trades: Consider FDUSD. Zero-fee promotions are very worthwhile for large trades. You can buy USDT first, then convert to FDUSD on Binance (usually 1:1 free conversion), and trade with FDUSD.
Long-term stablecoin holding: USDC has the highest transparency and most rigorous audits, suitable for risk-averse users.
Cross-platform use: USDT > USDC > FDUSD. USDT is universal across all platforms; FDUSD is mainly within the Binance ecosystem.
How to Convert Between Them
On Binance, the three stablecoins can be easily exchanged:
- Use the Convert feature, select USDT → FDUSD or other combinations
- Usually 1:1 exchange, free or minimal fees
- Instant settlement
So there's no need to stress about which to buy initially — you can switch between them at any time.
Risk Disclaimer
Although stablecoins claim to be pegged to $1, they're not entirely risk-free:
- De-peg risk: Both USDT and USDC have experienced brief de-pegging events (price deviating from $1)
- Issuer risk: If the issuing company encounters problems, the stablecoin's value could be affected
- Regulatory risk: Stablecoin regulations are constantly evolving across jurisdictions
Don't keep all your assets in a single stablecoin — proper diversification is a good practice.
If you need mobile access, you can download the Binance app first.
Summary
USDT is the most versatile with the best liquidity; FDUSD has fee advantages on Binance; USDC has the highest transparency. For daily use, USDT is recommended as the primary choice, with FDUSD for large trades to save on fees. All three can be easily converted on Binance, so there's no need to overthink it.
