Non-Fungible Tokens, aka NFTs, are digital collectibles that exist on blockchain platforms like Ethereum. Most cryptocurrency is fungible, which means it can be broken down to units and treated like liquid assets. NFTs are unique and whole assets, and can be bought at one price and sold for another. People treat them similar to artwork or rare baseball cards. The danger, though, is we are currently seeing an NFT bubble. NFTs are selling for tens of thousands of dollars right as they become available, and will probably crash in value soon.

This YouTube video by Meet Kevin goes into more detail. NFTs hold great potential as artwork, property deeds, and contracts, that need no middlemen and can be enforced by impartial computer code. But the concept needs time to grow steadily; explosive growth in value almost always leads to a correction, so wait until then for the chance to buy low again.
