People buy NFT because their price grows even more than the price of other cryptocurrencies.
But like other coins or tokens NFT must be useful for people, it must use in some products.
In such conditions the price of Metaverse will continue to grow in the future.
I think that you are wrong. People create NFT and people buy NFT, because they heard or read a lot of stories where people sold NFT for solid amount of money. From their point of view, NFT is another example of easy money. They think, that exactly the NFT they have bought will be bought for a unbelievably high price. But to me NFT is another random possibility to earn something.
And I dont believe in metaverse. It looks like another virtual reality. Another. That is what confuses me. If it is another, that means there are others and new can be created. If something is not very unique and rare, I dont believe its value can grow by itself, but only can be pumped. Pumped like a bubble. We all know what happens to bubbles. They either deflate, or burst.
