Non-fungible Tokens (NFTs)

An NFT, or non-fungible token, is a type of cryptographic token on a blockchain that represents ownership of a unique digital or physical asset. Unlike fungible tokens such as Bitcoin or Ethereum — where each unit is interchangeable with any other unit of the same value — each NFT is one-of-a-kind and carries distinct metadata that differentiates it from every other token. NFTs can represent digital artwork, music, videos, virtual real estate, in-game items, collectibles, event tickets, and much more, with ownership and provenance recorded immutably on the blockchain.

The NFT market saw explosive growth in 2021, with high-profile sales of digital artwork and collectibles attracting mainstream media attention and billions of dollars in trading volume. Standards like ERC-721 and ERC-1155 on Ethereum define how NFTs are created and managed, and marketplaces like OpenSea, Blur, and Magic Eden facilitate their trading. Owning an NFT does not always confer traditional intellectual property rights over the underlying content — it typically represents a record of ownership on the blockchain, which may or may not come with additional rights depending on the creator's terms.

From a trading perspective, NFTs behave differently from fungible cryptocurrencies due to their uniqueness and the subjective nature of their value. The market for NFTs can be highly illiquid — finding a buyer willing to pay a desired price can take time, and prices can be extremely volatile. Some traders engage in NFT flipping, buying assets they believe are undervalued and selling at a profit, while others participate in NFT projects for long-term community benefits or speculative exposure to the creator economy. For algorithmic traders, NFT market data feeds and rarity tools are emerging as analytical resources for navigating this evolving asset class.
