Fungible, Non Fungible?

Non-fungible tokens, or NFTs, are unique crypto assets. They can be used to represent both tangible and intangible items. A tangible product is a physical object that can be touched such as a building, gadget, etc whereas an intangible product can only be perceived indirectly. Fungibility is the ability of an asset to be interchanged for another of an alike item for example gold, dollar, etc. Non- fungibility is the ability of an asset to be irreplaceable or unique for example art, etc.
