Getting benefits from NFT? Well, let's say you have a work, an easy example is your artwork... when your image has been uploaded to the internet, anyone can download it and reuse it, but with NFT... you will be able to prove that the image is yours, your NFT ownership certificate will be the official proof, even though your image has been screenshotted by someone else... so other people can't just use the image...
When you set a price for your image, you can transfer the certificate, many people's favorite marketplace is OpenSea, besides that when your work is sold to a third party, you will also get royalties... the amount is usually 10%, but that can be set in the NFT settings...
The point is you can get money when your image is really in demand by other people.
