How much is 1 billion Robux?

I'm curious to understand the monetary value of a significant amount of virtual currency. Specifically, how much would 1 billion Robux translate to in real-world currency? Given the fluctuating nature of cryptocurrency and the unique economics of platforms that utilize Robux, I'm seeking a ballpark estimate. Additionally, are there any specific factors that influence the conversion rate between Robux and traditional currencies, such as market demand or supply? Any insights you can provide would be greatly appreciated.
