Is UOS public or private?

Could you please clarify the nature of UOS for me? Is it a publicly traded cryptocurrency or is it privately held and managed? I'm trying to understand the accessibility and ownership structure of this particular digital asset. Additionally, if it's public, could you provide some insight into its trading platforms and market performance? On the other hand, if it's private, could you elaborate on its use cases and the entities that have control over it? Thank you for your assistance in clarifying this matter.
