I've had hard time understanding what NFTs are, because the explanations I have heard are basically describing the selling of nothing. Paying real money for basically nothing in return, without the consent of the artists that originally created the art being sold as an NFT. It sounds more like a scam than anything else...
Imagine, if you will: A picture on the internet.
And what you are buying, isn't the picture, but a receipt for the picture.
That's the simplest way to explain an NFT. It's literally just a moneymaking scam to part fools from their money.
Which is why it's funny to laugh at all the idiots buying those dumb ape nfts and then hopelessly crying out when someone "steals" it by right clicking and saving. Because you can't do shit. What you bought was not a picture, but a string of code that represents the picture on the blockchain. An overglorified reciept
