how many VR users can this platform support simultaneously?
is there a limited amout of space available in the ecosystem, so that scarcity is present?
They will probably have problems in the beginning if there are a lot of users. Just like in the early days of email, when someone attached a file in a mail, ''internet would crash''

I don't think mark.space will be that bad at the beginning but of course, there will be some bumps in the road.
But after beta and all i expect a smooth platform.
that's the purpose of a beta, to test out the platform and iron out any kinks. this should ensure a smooth launch.
