Introduction: The Stablecoin Battle Royale
In crypto’s volatile landscape, stablecoins like USDT (Tether) and USDC (USD Coin) serve as essential safe harbors. Pegged 1:1 to the US dollar, they enable seamless trading, hedging, and DeFi participation without exposure to wild price swings. But with both dominating the $130B+ stablecoin market, which reigns supreme? This in-depth USDT vs USDC comparison breaks down their differences in security, transparency, adoption, and real-world utility to help you make informed decisions.
What Are USDT and USDC?
