Does USD Coin lose value?

Could you please clarify for me? I've heard some rumors that the value of USD Coin might be fluctuating. Is there any truth to this? I'm trying to understand if investing in USD Coin is a stable choice or if there's a risk of losing value. Could you explain how the value of USD Coin is determined and if there are any factors that could potentially cause it to decrease in worth? I'm particularly interested in knowing if the value of USD Coin is backed by anything solid, or if it's more volatile like other cryptocurrencies. Thank you for your insights.
