NFTs are basically unique digital items that live on a blockchain, making them one-of-a-kind. They’re not interchangeable like Bitcoin or Ethereum, which is why they’re called “non-fungible.” These tokens can represent anything from art to video clips. If you’re curious about their value or trading, you can use sites like Paybis
