In March 2021, a digital artwork by an artist called Beeple sold at Christie's for $69 million. It was a JPEG. This event — baffling to most people, thrilling to crypto enthusiasts — was the moment NFTs became a mainstream conversation. Understanding what actually happened requires understanding what an NFT is, and isn't.
A pound coin is fungible — every pound coin is identical and interchangeable. A fungible token (like Bitcoin) works the same way: any 1 BTC equals any other 1 BTC. A non-fungible token is unique — each token has distinct properties and cannot be replaced by another. Think of it like the difference between a £20 note (fungible) and a signed first edition of a book (non-fungible — that specific copy has specific value).
An NFT is a unique token on a blockchain (usually Ethereum) that points to a piece of content — an image, video, audio file, or other digital asset. The blockchain record proves who owns the token and tracks every transfer. What it doesn't do: give you ownership of the underlying image file. The JPEG usually sits on a server somewhere — the NFT is a receipt pointing to it.
The ownership illusion: most NFTs store the actual media off-chain — on a server, an IPFS node, or sometimes just a URL. If that server goes down, your NFT still exists on the blockchain but points to nothing. The right-click-save criticism is partly unfair (you don't have the provenance record), but the "you don't actually own the art" criticism is mostly accurate for most NFTs.
NFT trading volumes exploded in 2021, peaking at around $17 billion in Q3 2021. Bored Ape Yacht Club NFTs that sold for $200 were trading at $400,000. CryptoPunks were considered "blue chips." Celebrities endorsed collections. Three months later, most collections had lost 95%+ of their value. Trading volume collapsed. The vast majority of NFT projects from that era are now worthless.
What drove the bubble: a combination of genuine early-adopter excitement, celebrity marketing, speculative FOMO, and significant wash trading (buying from yourself to create artificial volume and price history).
Stripping away the speculation, NFTs do solve a real problem: proving digital ownership and enabling verifiable provenance. Genuine applications that have shown durability:
The honest assessment: the 2021 NFT market was overwhelmingly speculative. Most NFTs from that era are worthless. The underlying technology has legitimate applications that are slowly being built. Whether "NFT" as a brand survives or the technology gets re-labelled is a separate question from whether the use cases are real — some are.
