What is facebook changing their name to? Is it a good metaverse domain? Metaversex is alright, here is a sample of the keyword + x sales results at namebio:
I think the 'meta' + something will work better in the long term than the full 'metaverse' + something as in domains usually shorter is better. But I see many people registering 'metaverse' + something.
It will very much depend on the specific quality of the metaverse domain.
Some will make money, maybe even 6 or 7 figures USD, but many other domains will never be sold.
