I think NFTs cоuld be the most useful thing in crypto we've seen yet.  Probably a decade away from where it needs to be though.  People keep looking at them like they're nothing more than .png files, but the art is actually the least interesting thing about NFTs.  The added functionality they're going to bring to things like the events tickets market are going to cause some real world changes and make things better for people.  Not just crypto people either, but mainstream folks will benefit from NFTs being used in society.  Most people don't get this.
