Stablecoins: Meaning, Examples, Use Cases, and Risks

Stablecoins have emerged as a pivotal component in the cryptocurrency ecosystem, offering a bridge between the volatile world of digital assets and the stability of traditional fiat currencies. By pegging their value to external references like the US Dollar or commodities like gold, stablecoins aim to provide consistent value, making them an attractive option for investors, traders, and everyday users.


Key Takeaways

  • Stability Meets Crypto: Combines the benefits of cryptocurrencies with the price stability of traditional money.
  • Popular Examples: Tether (USDT), USD Coin (USDC), Dai (DAI), and Ethena USDe (USDe) dominate the market.
  • Versatile Use Cases: Ideal for transactions, decentralized finance (DeFi), remittances, and hedging against volatility.

What Is a Stablecoin?

A stablecoin is a cryptocurrency designed to maintain a fixed value relative to an external asset, such as:
Fiat currencies (e.g., USD, EUR)
Commodities (e.g., gold, oil)
Cryptocurrencies (e.g., Ethereum-backed collateral)

Unlike Bitcoin or Ethereum, which experience high volatility, stablecoins aim for price consistency, making them suitable for:
– Everyday payments
– Savings
– Risk management in crypto trading

How Stablecoins Maintain Their Peg

Stablecoins use four primary mechanisms:

  1. Fiat-Collateralized: Backed 1:1 by reserves (e.g., USDT, USDC).
  2. Commodity-Backed: Pegged to assets like gold (e.g., PAX Gold).
  3. Crypto-Collateralized: Overcollateralized with crypto (e.g., DAI).
  4. Algorithmic: Adjusts supply via smart contracts (e.g., former TerraUSD).

4. Everyday Transactions

Businesses and freelancers increasingly accept stablecoins for payments due to low fees and instant settlements.


Risks of Stablecoins
