I think they will use utitlity tokens to pay for services and purchases inside the VR.
Does the token have holding value where people can get something by holding it or perhaps there is a mechanism to support and increase the token price? If there is anything rather than just relying solely on the law of supply and demand.
Other than renting your space in the virtual world it would be nice to have some kind of reward for the holders because not every holder would own land.
