Is USDC high risk?

Could you please elaborate on the risk profile of USDC? I've heard some conflicting opinions about its safety, and I'm trying to get a clearer understanding. Is it considered a high-risk investment? And if so, what are the main factors that contribute to this risk? On the other hand, if it's considered relatively safe, what assurances or mechanisms are in place to mitigate potential losses? I'm really interested in understanding the nuances of investing in USDC and how it fits into my overall portfolio.
