Theory of money: From ancient japanese copper coins to virtual currencies

Abstract

Currently, virtual currencies are targets of speculative activities and subject to many other problems. If, however, an ideal virtual currency can be realized, it is expected that it will add a whole new dimension to our economic activities. Virtual currency is very similar to deposit currency in that data is used as money. While deposit currencies are centrally controlled by banks and other financial institutions, virtual currencies are maintained in a decentralized manner by many people. Through decentralization, significant cost savings can be realized.
