In the virtual currency market of $BTC , USDC (USD Coin) is a prominent presence. It is an open-source crypto stablecoin pegged 1:1 to the US dollar, launched jointly by Circle and Coinbase, with each USDC backed by a corresponding dollar held in a regulated account.

Its advantages are clear: strong stability, unaffected by significant fluctuations in the crypto market; high liquidity, widely traded on mainstream exchanges; and good practicality, usable for various crypto transactions and payments. However, it also faces challenges, such as centralization issues and significant impact from regulatory changes. Recently, it received approval in Japan, with a market capitalization of $56 billion, and may play a greater role in payment and other fields in the future.
