Metaverse project developers can do that, call it sandbox, the team doesn't need to create Sandbox coins, they just need to add Bitcoin, for programmers it can be done, we can use NFT and Metaverse with Bitcoin payments, for now there is none who developed the Bitcoin network for the Metaverse.
There are many new projects, but I think bitcoin will exist.
We all see metaverse, NFT, Defi web 3.0.
But Bitcoin is remaining bitcoin.
Bitcoin is always be the King of crypto currency
