I really don't get the NFT thing myself, but things don't need to have physical value to be valuable.I can’t see it.
The whole thing is a con. Manufactured scarcity of a resource that no one is actually interested in.
With gold, or any other real resource, you can’t just decide to magically generate more different types of it and start your own business selling your own variety of gold.
That’s basically what crypto is trying to do - and the only reason it’s worked at all so far is that there are plenty of suckers who want to get in on the ground floor of something they think is going to fly.
NFTs are the daftest subset of all. While free image / audio / video formats are a thing, and they always will be, there’s literally no reason to pay for something that’s functionally equivalent. Except because you think it will somehow magically go up in value.
It’s a Ponzi scheme, and it’s over.
Anyone can spend 99p for a copy of the Mona Lisa, the physical value of the original is probably not much more. But the artistic and emotional value makes it worth millions.
