## FAQ: USDT and USDC Explained
### Is USDT safer than USDC?
No. USDC’s transparent reserves and regulatory compliance generally make it lower risk. USDT carries higher counterparty risk due to opaque holdings.

Usually not. Exchanges like Kraken charge 0.1-0.2% conversion fees. Cross-chain swaps may incur gas costs.
### Which has higher trading volume?
USDT dominates with $50B daily volume vs USDC’s $5B (CoinMarketCap 2023 data). Most BTC/ETH pairs use USDT.
### Are both stablecoins FDIC-insured?
No. Neither provides FDIC insurance, though USDC reserves include cash in FDIC-insured banks (not covering token holders).
### How do I store them securely?
Use:

## Final Verdict
USDT offers unparalleled liquidity for active traders, while USDC provides superior transparency for risk-averse holders. Diversifying between both mitigates single-point failure risks. As regulatory scrutiny increases, USDC’s compliant approach positions it for long-term growth, though USDT remains indispensable for global crypto markets. Always verify audit reports before large allocations.
