In the virtual currency market, USDC (USD Coin) is a highly notable presence. It is an open-source cryptocurrency stablecoin, pegged to the US dollar at a 1:1 ratio, jointly launched by Circle and Coinbase, with each USDC having a corresponding US dollar held in a regulated account.

Its advantages are obvious: strong stability, not significantly affected by the large fluctuations of the crypto market; high liquidity, widely traded on major exchanges; and good practicality, usable in various crypto transactions and payments. However, it also faces challenges, including centralization issues and significant impacts from regulatory changes. Recently, it received approval in Japan, with a market value of 56 billion USD, and may play a larger role in areas such as payments in the future.
