The truth in all this, nothing that has to do with governments and policies of government entities should enter, because the metaverse is free and should always be like that, however it is how you say it, the Digital Yuan will put it there whether they want it or not want, and be careful if also the Ruble, for me these things are going to be taken by them to have even more control, I hope that in the metaverses there are not so many demands from the KYC, in the same way they will see that the Chinese government will do everything possible so that the Chinese Yuan also arrives at the world level, and since there are so many rumors that there may be a world crash in the economy, that scenario may occur.
I personally believe that is unlikely the Russian Ruble would appear within the Chinese Metaverses o Metaverse. I don't see Russia handing over the control or authorization to China to commerce with their currency to that level, Russia does not have that infrastructure, China does.
Also, since the Metaverse in general is being marketed as something more than a MMORPG like several games we have seen since the 2000s, I expect both western and eastern Metaverses to ask for KYC, because it is not about having fun in a video game anyone, it is about the integration of virtual reality into tasks like shopping, learning, working, etc. In that sense, those activities obviously require full KYC to function.
