What is Money? Money simply explained
In order to understand bitcoin as a medium of exchange as well as a store of value, one must first understand money fundamentally. Although we use it every day, this question is surprisingly difficult to answer as to what exactly money is.
The simplest way for people to exchange value is through the mutual direct exchange of goods. This process of direct exchange is also known as barter. However, this is only practical in a small ecosystem, but it can also become a major disadvantage because the needs of both parties cannot always be satisfied.
In a complex global economy, your need a neutral good that serves as a medium of exchange.
Money is basically distinguished between commodity money and fiat money.
Commodity money, such as tobacco, shells, or gold usually has intrinsic value in addition to its exchange value, in the form of the commodity itself.
Fiat money, on the other hand, is national currency issued by the government, such as U.S. dollars, euros or Swiss francs. The value derives from the existence of the government and the national bank that issued it.
We use money to communicate value, to express to each other how much we value a product, a service, a gesture.
Historically, different cultures and regions have used different neutral mediums of exchange. For example, shells, tobacco, gold, silver, paper or bitcoin came into use as money or means of payment.
Modern economies are fundamentally based on fiat money. It has no intrinsic value in itself, yet it serves as a means of payment for goods and services in today's society. It is accepted because people trust that the responsible central bank will manage well and thus keep the value of money stable in the long term.
If central banks were to fail in this task, fiat money would lose its general acceptance as a medium of exchange and would also no longer be attractive as a store of value.
Money fulfills three functions. As a medium of exchange in trade with other parties. In its function as a unit of account, it forms a reference and facilitates the comparison of goods and services in terms of value. As a store of value, money enables people to save and thus maintain their purchasing power.
As a general neutral medium of exchange and payment, money is used to exchange goods and services. It facilitates the exchange of goods between parties.
A unit of account allows the value of all goods and services to be expressed in one unit and thus made comparable. Money acts as a measure of value.
The store of value function enables saving. Specifically, saving means that money received does not have to be exchanged for goods or services in a timely manner. Instead, one saves one's capital and obtains goods as well as services at a later point in time. Purchasing power should be maintained in the process.
In order to fulfill the above functions, money should also be durable, transferable, divisible, fungible, verifiable, as well as have a certain stability of value. At the same time, one of the most important factors, the quantity must be subject to scarcity.
