Why USDC instead of USD?

I'm curious, why should we choose USDC instead of USD? I've always been using traditional fiat currencies like the US dollar in my daily transactions. It's widely accepted, stable, and easy to use. So, what exactly is the advantage of opting for USDC, a stablecoin pegged to the US dollar? Is it because of the added layer of convenience it provides in the blockchain world? Or is it the potential for faster transactions and lower fees? Or maybe it's the innovative features like programmability and interoperability that attract you? I'm also wondering about the risks involved. Since USDC is a crypto asset, it's subject to the volatility and uncertainties of the crypto market. How do you balance the potential benefits with these risks? Lastly, I'd like to know about the practical use cases of USDC. In what scenarios do you find it particularly useful? Is it for cross-border payments, decentralized finance applications, or something else? I'm eager to hear your thoughts on this topic.
