The most apparent advantage of this technology goes to art workers. Firstly, they digitize their works and confirm their rights to an image, video, track, etc. Furthermore, they can earn by selling their NFT. In addition, if after the sale a buyer resells the object, the author receives royalties.
There are beneficial applications for customers:
Purchase an NFT from a famous person and resell it at an increased price
Buy non-fungibles and instantly resell them for other cryptocurrencies at a higher price
Make an NFT portfolio similar to an investment portfolio and receive dividends
