How much VP is 50 dollars?

Excuse me, I was wondering if you could clarify something for me. I'm a bit confused about the value of virtual points, or VP, as it relates to dollars. Specifically, I'm trying to understand how much VP would be equivalent to 50 dollars. Is there a set conversion rate, or does it vary depending on the platform or exchange? I'd appreciate any insight you can offer on this matter. Thank you in advance for your assistance.
