What is Stablecoin?
Cryptocurrencies like Bitcoin and Ethereum experience continuous price fluctuations.
A stablecoin bridges traditional fiat currency with crypto by targeting a pegged value (e.g. $1.00 USD).
Popular fiat-backed stablecoins (USDT, USDC) hold reserves in cash, bank deposits, and US Treasuries, though reserve compositions vary by issuer.
Why It Matters in Web3 & Crypto
Stablecoins enable instant global settlement and capital preservation, though holders face issuer credit risk and potential depeg risk (e.g. USDC trading near $0.88 during the March 2023 banking crisis).
Key Mechanics & Best Practices
- 1Hold stablecoins to protect capital or lock in trading profits without leaving the blockchain.
- 2Use stablecoins as quote pairs for trading digital assets.
- 3Review monthly reserve attestation reports from independent accounting firms.
Practical Scenario
After taking profit on a crypto trade, an investor converts gains into USDC to maintain a stable digital dollar position.
SECURITY & RISK TIP
Distinguish between reserve-attested fiat stablecoins and uncollateralized algorithmic stablecoins, and monitor attestation reports regularly.
