You can screenshot or just download a copy of the digital art. But its the NFT (token you store in your wallet) that certifies that you own the original of that artwork. You can take it just like the original Picasso versus its print. The NFT simply validates you as the owner of the original artwork. The NFT (token in your wallet) is not the artwork, it’s just a cryptographic token that proves you’re the owner, and its safely stored on a blockchain. So owning an NFT is safe.
