> Most of the NFTs now are like trading cards, at least the successful ones. Why is there so much hate for digital trading cards?
From what I heard on artist communities, the huge electric energy demand that doesn't scale well. I like the possibilities NFT creates for fine art creators, but I'm more concerned about the ecological issues here.
As for the ecological impacts, Ethereum is primarily used as the basis for almost all NFTs. Ethereum currently uses Proof of Work like Bitcoin which spends lots of electricity to achieve decentralization. Unlike Bitcoin, Ethereum has spent years developing Proof of Stake as an alternative. You can follow the progress here: https://ethereum.org/en/developers/docs/consensus-mechanisms....
Proof of stake should dramatically decrease the electricity requirement of Ethereum.
