For me this kind of business has nonsense, why would someone pay half a million for a digital house? or more than 1 million for a tweet... The only sense I could find with this kind of business is money laudering.
This is what the others do lack of -- Appreciating one thing's value. Do you ever wonder why there are so many people that are onto NFTs? It is simply because they know that we are on digital era and most of things that would be valuable in the future would remain intact in the internet. Therefore, it is not really unique nor a weird thing to see that others are spending tons of their money as we all have different approach on thing that we see has a value and those who doesn't see any inch of it.
