How much vp is 20 bucks?

Excuse me, could you possibly clarify what you mean by "vp"? I'm assuming you're referring to some form of virtual currency or points, but the acronym "vp" isn't immediately recognizable to me without further context. Is this related to a specific game, platform, or cryptocurrency? If so, the conversion rate from US dollars (bucks) to these virtual points can vary widely depending on the system in question. Could you please provide more information about the context in which you're asking this question? That way, I might be able to give you a more accurate answer.
