I do not use VR to play gambling or other activities because, according to this article https://www.gamblingsites.com/online-casino/virtual-reality/, you need $399 to buy the equipment and people who do not use VR, they will not buy that because that is too expensive for them. They can still play gambling without using any equipment and enjoy the games. Maybe if the VR equipment can reduce in the future, they will try to buy it to feel a new experience playing gambling using VR equipment.

I haven't played in any such platform. Searching for it I got to know about a platform Slots Million. Looks like it doesn't accept cryptocurrency. From the article it is mentioned about 40 VR games are available since 2014. I don't know how far this is true. In some locations the casinos seems to provide this service, but through online gambling sites it isn't an easy thing to make things work with perfection. Because there is certain requirements for the flawless functioning, but users will try even without that. This will create issues on the user end making complaints over the platform.
