Ok, so the Roblox currency, robux, has a feature called the creator exchange rate where the creators of a game get robux from the people who spend the robux and can turn these robux into the Roblox admin for real money. Previously, the exchange rate was 250$ for every 100,000 robux. However in 2017, to adjust for inflation, they changed this to 100,000 Robux for 350$. The rate of inflation in US Dollars however would dictate that this is not equal to 250$ in 2007 (the year this function was added) but rather 286$ in 2007. Meaning that as the value of the US dollar decreases, and the value of the Robux increases to match, that Robux is slowly becoming more valuable than real US Dollars. Making Robux the cryptocurrency of the future.
