$USDC
As of May 8, 2025, USD Coin (USDC) remains a cornerstone of the stablecoin ecosystem, maintaining its peg at $1.00 with a market capitalization of approximately $60.9 billion and a 24-hour trading volume around $10.49 billion (coinbase.com). USDC's circulating supply has grown to 61 billion, reflecting a 78% year-over-year increase, outpacing other major stablecoins (circle.com). This growth is bolstered by institutional adoption and the expansion of the stablecoin market, which has reached a total market capitalization of $243 billion (coinbase.com). However, the stablecoin sector faces regulatory uncertainties, as U.S. lawmakers debate the GENIUS and STABLE Acts, with concerns over money laundering and financial system risks causing some Democrats to withdraw support (politico.com). Despite these challenges, USDC continues to play a vital role in digital finance, supported by its strong market presence and institutional backing.
