To be honest, I haven't understood the cause of NFT fire so far.
The fire caused by the uniqueness of NFT. Others may have different opinion than you. When you're saying that's ugly but people may see that from the different view like it has only a few NFT. You can see cryptopunk or something else. Some people were judging this kind of NFT has no value but people who bought it has different reason.
I looked at those NFTs. They were so ugly that I had to 1eth. I began to doubt my aesthetics.
NFT market was a free market, when you're seeing an ugly picture that valued at 1 ethereum and that's the price created by the owner of such NFT. You can't put the standard value on it as the creator of NFT itself will be offering what rate that will be suitable for his own NFT to be bought by others. I think that you must understand about this reason.
