What is a collectible/NFT?

Collectibles, often referred to as NFT (Non-fungible Token). Compared with BTC and ETH and other fungible assets, NFT is a unique and indivisible asset. For example, Cryptokitties and tokenized digital tickets etc. are all in the NFT category. Due to its features as non-homogeneity and inseparability, NFT can anchor the concept of goods in the real world, such as tokenized tickets, high-value wine and jewelry with unique designs.
