It’s possible that mainstream artists might benefit the most from NFTs overall but I think there’s room for indie musicians as well. It depends on your type of audience and how much they’re into this NFT space. For instance, Shawn Mendes made less money than a less known artist like Dj Blau with his NFT collection. It might be that Mendes’ fans are not so savvy about this space, compared to Blau’s fans into electronic music, and they don’t value it as much as the latter. I think there’s room for everybody ;)
