How much is a roco?

Excuse me, could you possibly clarify for me what exactly a "roco" is in this context? Is it a unit of currency, a cryptocurrency perhaps, or is it referring to some other form of financial instrument or asset? If it is indeed a form of currency or cryptocurrency, could you provide me with some insight into its current market value? Additionally, is there a specific exchange or platform where one might go to buy or sell "rocos"? I'm quite intrigued and eager to learn more.
