When choosing between stablecoins, the debate between USDC and Tether dominates conversations among cryptocurrency users. As the two largest stablecoins by market capitalization, both USD Coin (USDC) and Tether (USDT) aim to maintain a stable $1 peg; however, they differ significantly in terms of transparency, regulatory compliance, and market adoption.
Understanding the Stablecoin Landscape
Stablecoins are digital currencies designed to maintain a stable value by pegging to the US dollar. They serve as essential infrastructure in the crypto ecosystem, providing stability in an otherwise volatile market while enabling seamless trading, remittances, and DeFi participation.
