I am completely frank right now, I just don't understand why someone creates garbage and why someone pays tons of money on it?

I found this ordinal on okx.com
Can anyone really explain, why does it have value and why does someone buy it? Is it a masterpiece? No, it's a piece of garbage. Why should someone pay bitcoins in it? And if we keep in mind that mempool is spammed, then it means that tens of thousands of people create this garbage every day. I have never seen any masterpiece listed on NFT marketplace, there are only pixelated shits everywhere.
Looks like you grabbed some pictures of the "Goosinals" NFT-Collection.
You can check
magiceden.io for some other collections aswell - the Bitcoin Frogs for example have a floor price of atleast .0604
BTC and people are still buying them.
The bad thing is that in addition to the original rip-off, there are other scams with fake markets. If you don't pay attention and sign it incorrectly, the entire wallet will be drained.
It might sound primitive at first but newcomers in particular often fall victim to it.
Also, why are pixelated arts popular instead of arts like Da Vinci's Last Supper, Salvador Dali's The Persistence of Memory, The tower of babel by Pieter Bruegel the elder and so on.
It's just kind of a fake market that has been artificially inflated by the creators. Many people are blinded by supposed sales and dont realize that they are also manipulated.
You cant seriously believe that some prices have actually been realized.

Newcomers in particular are blinded by these quick transactions. Und dann schnappt die Falle zu.
