As a newcomer to the cryptocurrency space, the first type of digital asset you should understand is stablecoins.
What Are Stablecoins?
Stablecoins are tokens pegged to the US dollar, primarily based on the ERC20 standard (though now extended to multiple blockchains). Technically, they function similarly to altcoins but with one critical difference: stability. Stablecoins maintain a near 1:1 ratio with the US dollar, with fluctuations typically under 0.1%.
The most prominent example is USDT (Tether).
Why Stablecoins Matter
Here are two key questions to address:
- Why do we need stablecoins?
The crypto market hosts thousands of volatile tokens. While direct swaps between tokens are possible, their price instability necessitates a stable benchmark for valuation and trading—similar to traditional currencies. How do cryptocurrencies achieve stability?
Historically, many stablecoins failed. Today, stability is achieved through:Centralized Backing: Examples include USDT (Tether) and USDC, issued by centralized entities claiming 1:1 USD reserves.
- USDT: No public audits, yet dominates the market (~95% usage).
- USDC: Regularly audited but suffered a temporary depeg to $0.85 in March 2023, eroding trust.
Decentralized (Algorithmic) Models:
- DAI: A decentralized stablecoin by MakerDAO, backed by collateralized crypto assets.
- Others like LUSD or sUSD exist but hold minor market shares.
💡 Fun Fact: If USDT collapses, the crypto market could regress by years due to its foundational role.
Are Stablecoins Truly Stable?
Stablecoins have faced multiple crises:
- USDC’s 2023 Depeg: Dropped to $0.85 amid banking sector turmoil, recovering later but losing adoption.
- USTC’s Collapse (2022): An algorithmic stablecoin offering 20% yields, it crashed irreversibly, devastating Korean investors.

FAQs
Q: Why are most stablecoins tied to the USD?
A: The USD is the global reserve currency, making it the logical anchor for borderless blockchain systems.
Q: Can USDT fail like USTC?
A: Possible but unlikely due to its entrenched usage. However, its lack of transparency remains a concern.
Q: Is DAI safer than USDT?
A: DAI’s decentralized model reduces counterparty risk but depends on crypto collateral volatility.
Key Takeaways
- Stablecoins bridge crypto volatility with fiat stability.
- USDT dominates despite opacity; USDC and DAI offer alternatives.
- Historical failures (USTC) highlight risks even in "stable" assets.
