The supply of gold on earth is finite. An infinitely growing cryptocurrency presupposes perpetual economic growth, which requires ever increasing population and resource extraction. Maybe that's realistic if we start colonizing Mars and mining asteroids, but it's not possible on earth alone. If limited supply turns out to be an issue, competing currencies can be used to augment supply, it's basically already the case.
