When it comes to stablecoins, many people's first reaction is USDT, but there is actually a low-key powerhouse - USDC.

This thing can be simply described as "on-chain USD." Circle created it in 2018, and the core logic is very straightforward: you deposit 1 USD, and they mint 1 USDC for you; if you want to exchange it back for USD, you can do so at a 1:1 rate anytime. Sounds like nonsense? The key point is that there is real money backing it—Circle puts all the received USD into high liquidity assets, not into trading coins or lending, which is completely different from some stablecoins with "mysterious reserves."

What does it feel like to use it? Transfers basically arrive in seconds, the fees are low enough to be negligible, and it's available year-round—while traditional banks close on weekends, USDC still operates in over 180 countries. Want to send money from New York to a friend in Tokyo? It takes a few minutes, no need to wait for T+2 settlement, and no middlemen taking a cut.

More importantly, this thing is under the watch of U.S. financial regulation, not a wild project. For institutions, compliance can help them avoid many pitfalls; for ordinary users, at least they know their money is not sitting in the wallet of some anonymous team.

Of course, a stablecoin is still a coin, and the decoupling risk always exists. However, based on the current market position and transparency, USDC is among the group that has solidly established the concept of "digital age dollar."
