Crypto is also about art, and not only about storing numeric value.
If we want to achieve a higher adoption, Art, NFTs etc. should also become possible on the btc network.
And not just left for the world of alt coins.
Not art, because they have flaws that have been completely exposed by Ethereum NFTs (people will just abuse it to make what I call "lazy art", to make a quick buck, which screws over the buyers in the process, which gives the entire NFT system a sour taste in people's mouths.
Much better is for a layer on top of Bitcoin to be used for genuine seals/stamps of approval issued by private companies for their own products.
