The cryptocurrency market is highly volatile. For example, Bitcoin (BTC)—the most well-known cryptocurrency—can easily fluctuate over 10% in a single day or 50%–100% within a month.
This raises a question: If cryptocurrencies lack stable value, how can they function as practical currencies?
The answer: They currently don’t—at least not as mainstream payment methods.
For now, fiat currencies (government-issued money like the USD or EUR) remain dominant in pricing goods and services.
Here’s where stablecoins (Stablecoin) come in.
They act as hedge assets in the crypto market, mimicking the stability of fiat currencies while retaining blockchain’s fast transfer capabilities.
Today, stablecoins hold massive market shares:
- USDT (Tether): $110B market cap (3rd-largest cryptocurrency).
- USDC (USD Coin): $32B market cap (6th-largest cryptocurrency).
Understanding stablecoins is essential for anyone entering crypto.

What Are Stablecoins?
Stablecoins (e.g., USDT, USDC) are cryptocurrencies pegged 1:1 to fiat currencies (like USD/EUR) or other assets (e.g., gold, crypto).
Key Features:
- Price Stability: Minimal volatility vs. traditional cryptos.
- Collateral-Backed: Most are backed by reserves (e.g., cash, crypto).
- Fast Transactions: Enable quick swaps between cryptos/fiats.
Functions of Stablecoins

- Swap Bitcoin → Stablecoin (e.g., USDT) instantly vs. slow fiat conversions.
Lower Costs

Value Storage

Pricing Unit
- Trade pairs like BTC/USDT (more liquid than BTC/USD).
Types of Stablecoins
| Type | Backing | Examples | Risk Level |
|-----------------------|-----------------|----------------|------------|
