How to buy and sell NFTs | What are these tokens

NFTs or non-fungible tokens are digital assets that are unique and cannot be replaced by something else of equal value, unlike fungible assets like cryptocurrencies. They use blockchain technology, which is a decentralized and public ledger that records transactions. NFTs have gained popularity in recent years and have been used to represent various digital assets, including art, music, and collectibles.

One example of NFT's popularity is the sale of an NFT by digital artist Beeple for $69m (£50m), which set a new record for digital art. Additionally, French firm Sorare, which sells football trading cards in the form of NFTs, has raised $680m in funding, highlighting the increasing demand for NFTs.

NFTs themselves don't usually contain digital assets; instead, they serve as a digital certificate of ownership that represents ownership of a digital asset stored elsewhere. This means that the stability of an NFT is only as stable as the computer or network that stores the asset file.

In summary, NFTs are digital assets that represent unique items and are stored using blockchain technology. They have gained popularity in recent years and have been used to represent various digital assets. However, their stability is dependent on the computer or network that stores the actual asset file.
