I thought the most annoying thing about NFTs is that you're basically buying a hyperlink to a website that you do not control.

I checked out the Doctor Who NFT thing after Team 17 was teaming up with the people behind that thing, and the domain where the NFT metadata and images are being hosted was due to expire next summer. They didn't even splurge on a five-year registration for the domain. Hopefully auto-renewals don't stop working.
