We can describe an NFT as a cryptographic token that defines an asset uniquely. It can represent both a digital asset such as an image, but it can also track real-world assets, such as a house or car, or a song, for example. As you can uniquely define assets, this means you can also prove ownership over said assets, and moreover, prove their authenticity.

The problem with regular tokens created using the ERC-20 standard is that they are divisible and can be interchanged. We don t want this property for tracking unique assets. This would mean you can divide your digital image or physical car into different tokens and distribute it. That would defeat the whole purpose of non-fungible tokens, as you want only one of them pointing to a single asset. Moreover, if we can make copies of tokens, it becomes impossible to uniquely define them. For that reason, non-fungible tokens solve the interchangeability problem

The three properties that make NFTs so desired are uniqueness, rarity, and indivisibility. What makes NFTs unique is that NFTs allow you to uniquely define an asset by providing metadata that describes the asset and sets it apart from other assets. What makes NFTs rare is that with NFTs, it's not possible to infinitely create new assets. Rarity makes sure that you can only define each asset once on the blockchain, which makes NFTs so desired among collectors

This can be one of many things. The simplest of which would be your love for the Art or creator you want to support. We can also look at the utilitarian value as a big draw for many creators.It is also bought for its uniqueness. If you own an NFT edition of an artwork, that would make you the only person in the world to own.
