Most cash or cryptocurrency is not supported by society. In fact, most cryptocurrency is not associated with any commodity. They only cost when people believe that they are worth it. From the very beginning, cryptocurrency has taken the cash system as a foundation and changed only slightly on decentralization and anonymity. Its value depends on the community using cryptocurrency. If the number of users is quite large, the merchandise can be sold in this currency and if it is safe and stable, cryptocurrency will be valuable even if nothing is equivalent to it in the real world.
