The good... everything is good for Bitcoin. I've had dozens of Ethereum and NFT people reach out to me about running nodes. They are learning about UTXOs. There are a lot of positives with this. Ethereum and Solana won't be around, nor with the web sites hosting their NFTs in a decade. Bitcoin will be around for hundreds of years. It makes sense for them to preserve their artwork on Bitcoin compared to alternatives.

The bad... it's a peer to peer electronic cash system, not a file system. It's spam. They're paying 3/4 less by using an exploit or an unintended use of the system. If they were paying the same fees as the rest of us, then I wouldn't hate it. If they were not abusing the system, then I wouldn't hate it.

The ugly... This would be me telling someone how they can use Bitcoin.
