Each NFT was earned by the students after more than 13 hours of education about blockchain, cryptocurrencies, and NFTs. They are the expression of professional artists how they see the web 3 space. The important data for example the name of the student, the date of the masterclass, etc. are not written on the NFT but "in" the NFT. They are part of the Metadata. Even more, some parts of the Metadata are used by the artists to describe the web3 space even better. By that, the value of the NFT is not destroyed. Even more, each NFT is giving to its holder's access to a special postgraduate program with huge benefits.
