It might be a new craze, but i give only 10% that it would be anything based on a blockchain (any of them).
Most likely games, next some tech behemoth(s), but I have zero interest in Facebook or Microsoft "metaverses".
That said, i already own some "metaverse" properties, bought for a pittance in 2017.
However, I fully expect them to zero out eventually, as I don't have time to 'develop" anything there and so do 90-99% of other people.
Maybe upon retirement , I would open a bar/club on my props or something like that if i eventually would want to mess with that.
Additionally, there is no "floor" for metaverse properties, there is only 'ask', but no 'bid', so values cannot be realistically determined as people's asks for nearby parcels could differ by a factor of 20X.

TL;DR 'Metaverses' are full of it rn and it would take maybe a decade to have something interesting in those realms.
