What Is a Non Fungible Token?

When something is fungable, they're all the same. One dollar will always equal one dollar whatever the value of is at that time. Something that is non fungible means that each one of them is unique and different. There's no two that are the same. And if we start to layer on top of this other use cases, we can also talk about the trading, right? Because the moment you purchase something, and we're now transitioning really into nfts here, write non fungible tokens.
