I disagree with this 100%. Right now the projects that we have are not as good as that to justify anything in my portfolio. I can definitely get some if I ever want to, but right now none of them looks good enough and that means I could definitely avoid putting any metaverse projects on my portfolio and still feel alright about it.
That is why I believe that we shouldn't be considering anything as urgent, just consider the situation as "there will be a great project in the metaverse world in the future" and that will be when I will end up investing into it. That's not an easy task because it requires me to keep a watch on them, but none fits that bill right now.
Putting the metaverse project in the portfolio is a personal choice and becomes personal research. But for now, the metaverse project or other projects are still slumped and experiencing a drastic decline. I know some metaverse projects with P2E features that are deprecated and the project framework was changed in the end.
It is better to put Bitcoin and Ethereum in the main portfolio and it will definitely be better and become a long-term investment. For some other projects just need to do some research and be a personal choice. A serious project trying to continue to be developed will certainly rise and reach a period where the project reaches its peak.
