Unfortunately for NFT lovers, you are absolutely right, I've lost thousands of dollars on nfts on ethereum, I spent over 6 ethereum coins buying nfts on ethereum during the nft hype, if you remember the days of Dego mining and the rest, some of those nfts are still sitting in a wallet I've thrown away because there is absolutely no liquidity or demand for them, other nfts I staked on a mining platform and the platform shut down and there was no way to get back my staked nft, but even if there was a way, the nft also does not have any demand or liquidity to sell..
NFTS are very useless across almost all blockchain and this is because they come wit absolutely no utility, and those that come a utility at first usually don't have any sustainability measures to maintain that utility for long term so that the nft will maintain a long term value and demand as well, this is one and major reason why nfts are dead, even those that seem promising at first still end you dying.
I think a lot of people previously criticized NFT creation and the people buying those NFTs. Do you remember a guy who bought an NFT created from photos of his daily routine or something like that? Those NFTs do not have any value today. I bought some shitcoins to gain 100x, but I ended up holding them, and they went to zero at some point. It is the same as the NFT things.
You need to understand a simple thing: if it has no use cases, it is worthless. As for the Metawin NFTs, what can holders do with them outside Metawin? Probably, they will receive rewards from Metawin for holding the NFT, but what other benefits might they get? I think nothing.
