# NFT Types

Each Notebook NFT has a unique rarity that is established during the minting process or during the initial Notebook NFT sale. The total efficiency of Notebook NFT is increasing as its rarity grows.

There are also four different Notebook NFT types that are selected at random throughout the minting process. Each type is intended for a certain form of engagement within the community. Based on your participation efforts you will be able to customise your NFT and maximise your earning potential.

In order to maximise your earning potential, you must adhere to the minimum number of characters in the post. If you do not meet this objective you will not receive the full amount of $INK for your post.
