想問這題的C C選項指的不應該是說 買賣NFT比想像中複雜 但文中所指NFT的買賣那麼複雜,那為什麼不是錯的勒

第 39 至 42 題為題組 As we progress further into the digital age, new terms and technologies seem to pop up everywhere. The latest of these is "NFTs" or non-fungible tokens. If something is fungible, it means that it is able to be replaced by an item of identical value, such as currency. Therefore, a non-fungible token cannot be interchanged; it is unique. NFTs are linked to the blockchain-the digital database that supports online cryptocurrencies like Bitcoin and Ethereum. Let's take a deeper look at NFTs and how people can buy, sell, and trade them. In simple terms, NFTs are one-of-a-kind digital works of art. They can take the form of GIFs, tweets, virtual trading cards, images of physical objects, and more. NFTs tend to attract investors who believe in the future of blockchain technology, and who are willing to spend top dollar to obtain a new form of digital currency. For example, Jack Dorsey's first tweet sold for $2.9 million, a video clip of a LeBron James slam dunk sold for over $200,000, and a decade-old "Nyan Cat" GIF sold for $600,000. Clearly, the NFT market is something to be taken seriously. So, the next question is: how does one participate in it? modi naging dato Basically any digital image can be purchased as an NFT.
