In the dynamic world of cryptocurrency, stablecoins serve as a vital link between volatile digital assets and traditional fiat currencies. Among the most widely used options are USDT (Tether), USDC (USD Coin), TUSD (TrueUSD), and UST (TerraUSD). This guide breaks down their differences, use cases, and risks to help you make informed decisions.

Stablecoins are cryptocurrencies designed to maintain a stable value by pegging to a reserve asset, typically the US dollar. They offer:
- Price stability amid crypto market fluctuations.
