I also think that VR market will grow fast soon. As many said, in the following 2 years VR will probably be more present and a lot of people will use it, like blockchain I think. Mark.Space have some time to developp something big.
It is growing but the equipment is a bit expensive, if mark.space can have a mobile version of there platform that can be easily access by any VR capable smartphones that would be great.
I also see a huge potential in the VR technology.
As the VR becomes popular, I think the price will go down.
Ive just saw an ad this morning that promoted the Occulus Rift with Controllers for 449 which is an awesome price i think and a great drop from 799 initial price
