USDT vs USDC: Key Differences Between the Top Stablecoins

USDT vs USDC: What Are Stablecoins?

Stablecoins like USDT (Tether) and USDC (USD Coin) are cryptocurrencies pegged to fiat currencies, such as the US dollar, to minimize volatility. They bridge the gap between traditional finance and crypto, enabling fast transactions, remittances, and decentralized finance (DeFi) participation. But how do these two giants differ? Let’s break it down.

USDT vs USDC: 5 Key Differences

1. Issuer and Governance

• USDT: Launched in 2014 by Tether Limited, a company linked to the Bitfinex exchange. Controversies surround its reserve audits.
