Which non memecoin deserves more attention?

I'm asking due to the lack of non memecoins posts. (I'm not againt memecoins btw)

I want to disclose, this is not financial advise, this is only an opinion.

I'll start, I found NFTBooks, which has an awesome idea of making books as NFTs. I can't explain it easily so heres the whitepaper. I think the idea is awesome, a Blockchain solution for eBooks. My main concern, is if eReaders will be able to use NFTBooks due type of document (ePub, PDF, .txt…). The project it's on an early stage, but I'll keep an eye on the project, even if the price doesn't go up, as long it's not a scam.
