For me, NFT’s are an interesting alternative to ordinary digital downloads. Instead of trying to sell hundreds of copies here, I sell just one of each on an NFT marketplace. It feels more like traditional art. I don’t have to worry about sharing or stealing, there will only ever be one true original.
For the buyer there are also some unique benefits. Unlike just buying a digital download, you can buy an NFT, download the art, and then either hold the original in your own collection or resell it for profit (or loss – no guarantees 😊). It’s not quite as convenient as just using your credit card in a store (at first) but it is a lot more interesting.
