While many of us were forced to at least try to understand what an NFT is at some point in 2021 or 2022, the latest figures from Google Trends suggest that this research has not led to a sustained interest in the topic.
For those that didn't quite get around to it at the time, here's Wikipedia to the rescue: "A non-fungible token (NFT) is a unique digital identifier that is recorded on a blockchain, and is used to certify ownership and authenticity. It cannot be copied, substituted, or subdivided. The ownership of an NFT is recorded in the blockchain and can be transferred by the owner, allowing NFTs to be sold and traded."
Still not clear? Then have fun delving down this particular rabbit hole. Though if the trend shown by Google's search data is anything to go by, combined with the countless NFT-based scams that have been uncovered, that might turn out to be a monumental waste of your time.
