Digital collectibles are unique digital items that can be bought, sold, and traded online. They often use blockchain technology to verify ownership and authenticity, making them distinct from regular digital files. Examples include digital art, virtual trading cards, and in-game items, which can hold value similar to physical collectibles. These items are often represented as NFTs (non-fungible tokens), which ensure that each collectible is one-of-a-kind. Digital collectibles can be found on various online marketplaces, allowing collectors to showcase their collections and connect with others who share similar interests.
