Stablecoins are cryptocurrencies pegged to stable assets like fiat currencies (e.g., the US dollar). Among the top contenders, Tether (USDT), USD Coin (USDC), and Binance USD (BUSD) dominate the market with their combined capitalization. This guide breaks down their differences, use cases, and how to choose the right one.

- Price Stability: Minimal fluctuation compared to other crypto assets.
