In the fast-paced and often unpredictable world of digital finance, stablecoins have become a cornerstone of decentralized economies, offering a much-needed anchor amid market volatility. As demand for reliable digital assets grows, Tether (USDT) and USD Coin (USDC) emerge as two of the most trusted and widely used stablecoins—each pegged to the US dollar to ensure stability. While both aim to provide a safe haven in the turbulent crypto markets, they differ in critical aspects that could significantly impact your trading or investment strategy.
This guide explores the core features, benefits, and risks of USDT and USDC, along with practical steps to accept payments in these stablecoins.

Why They Matter:
- Reduce volatility compared to other cryptocurrencies.
