Non- Fungible Tokens are no longer a new phenomenon. Today there are many exhibitions, I have visited one of them in Dez. it was in Zurich.
NFTs are risky because their future is uncertain, sure you can win also a lot of money. Promised is they cannot be copied and falsified. So the original that is traded when an NFT is auctioned is not the artwork itself at all but this transaction proof. Here a couple of NFTs designed images in Circle.
Have a Great day!
