Why it matters: On other exchanges, converting USD to USDC costs trading fees (up to 1.2%). On Coinbase, it's $0. For a $10,000 conversion, that's up to $120 saved.

Frequently Asked Questions

USDC vs USDT — which is better? +

USDC is considered more transparent (monthly audits, US-regulated). USDT has more liquidity globally. For US users, USDC is generally preferred. For international trading, USDT often has better pairs and liquidity.

Are stablecoins actually stable? +

Major stablecoins (USDC, USDT) maintain their peg well but aren't risk-free. They can briefly depeg during market stress. The bigger risk is issuer solvency—make sure you trust the company backing your stablecoin.

Why use stablecoins instead of USD? +

Stablecoins move faster (24/7, no bank hours), work across exchanges and DeFi, and can earn yield. They're also useful for parking funds during volatility without converting back to fiat.

Is it safe to hold stablecoins long-term? +

For regulated stablecoins like USDC and GUSD, yes—they're backed by cash and short-term treasuries. USDT has faced more scrutiny about reserves. For large amounts, consider spreading across multiple stablecoins.
