This is new technology which is needed to develop for more years. And I really believe that there will be one became successful as many people now are in digital space, for now we see those projects in BETA but once they finish all the test they need we see them release the full version to the public. But if you are worried about the tokens which is created for metaverse then maybe its good for them not to hodl yet if you are afraid about volatility just focus on top coins at the moment since they are more tested.
However even if that is the case that does not mean the current projects that are being developed are the ones that will succeed, as we need to take into account that such a project will need massive amounts of resources for its development, and I think only huge companies like Facebook or Google have the technology, expertise and money to succeed.
