The rationale behind a Crypto currency is quite an ancient idea. In the absence of a central bank or in addition to it, people may choose to establish their own currency or currencies. The central idea is to secure assets (currently and in the future) as well as to enable an exchange between a community of people. The Museum of the National Bank of Belgium (image below) has a “Yap stone” on display which originates from the Pacific Yap Islands. Even very heavy and big stones served as wealth storage. The idealistic value of a particular stone conveyed additional value. In the true value of the word these people were banking on stone money in a way not to distant from what Crypto currency embodies today.
