Before a business can talk bouyantly about going on the Metaverse technology they have to begin first with the most trending technology with bitcoin and blockchain technology in its system before they can now advance into the Metaverse world and it's research, this is part of which i believe McDonald could also join among the reputable organization to journey along with this after their acceptance of bitcoin, they should serve a lesson for others to follow, one step at a time.
I can't seem to understand your point! It is blockchain and it is open source bro which means anybody can start from anywhere, it is not a must they have to own btc before joining the metaverse ecosystem. You make it sound like there is a guideline written somewhere by satoshi on how companies should approach adoption.
Maybe you are not following the metaverse news but believe me when I say it has gain more recognition from companies far known than McDonald. You should do more research on metaverse adoption to fully understand what I meant.
