I think NFTs are here to stay, same as the metaverse. I agree we should have a child board under the alt sections for Metaverse/ nfts.
While I agree that NFTs and metaverse are here to stay (like ICOs are still here, but now in form of IDO/IGO/INO/whatever), question is whether altcoin board is so overrun with them that having separate board is needed.
I would say no, and you can see on the screenshot below why there is no need for that. So, from the top 35 topics in
Tokens (Altcoins) board, only 6 (I may have missed one or two but doesn't change anything really) were about NFT based projects. Bare in mind that I even sorted them by the last post because situation would be even worse for NFTs if I let it to be sorted by default.
If situation was opposite then you would maybe have some argument that NFTs deserve their own board as they arw drowning everything else, but as we can see that is not happening as of yet, no matter the hype around it outside bitcointalk.
