For example: Let's imagine Fortnite, one of the largest MMOs in the traditional video game space, was built with blockchain infrastructure. V-bucks (the in-game currency used to purchase Fortnite assets) would have a value attached to it denominated in a reserve currency. At any time you would be able to cash out your V-bucks and exchange them for real money. The same goes for tokenized in-game assets like player skins or weapons. These assets would be NFTs (non-fungible tokens). NFTs are simply a form of tokenized ownership on the blockchain. In this case, you would own your Fortnite assets and have the liberty of trading them on the open market 24/7 in exchange for real money.
