1. What is money? Definition, characteristics and meaning
Money is a universal and generally accepted means of exchange that is used within a society to pay for goods, services, or to settle debts. It doesn't matter whether it is cash, paper money, digital money in a bank account or a cryptocurrency such as Bitcoin — as long as all parties accept it as a value carrier, it meets the basic requirements for money.
In modern economies, money serves as a central link for economic exchange. Without a uniform means of payment, modern markets with millions of products and services would be hard to imagine. But for money to survive in this role, it must have certain characteristics: It must be divisible, durable, scarce, uniform, sustainable and accepted. In addition, trust in its stability and purchasing power is essential. Without these qualities and without this trust, money would be worthless — regardless of its form.
2. History of money: From barter to digital money
The story of money is a story of human creativity and economic necessity. In the early period, people made use of barter. In the process, goods such as food, tools or raw materials were directly exchanged for each other. As long as two people each had something that the other person needed, this system worked.
But barter had significant disadvantages: It was inefficient, inflexible and dependent on a double coincidence of needs. What to do if you have grains to offer but your trading partner would prefer fish? To solve this problem, people began to use universal means of exchange — such as shells, stone discs, animal skins, or precious metals such as gold and silver.
Over time, this has developed into fiat money — a state-issued currency whose value is no longer backed by tangible assets such as gold, but is based on trust. Paper money in particular enabled easier handling and greater transportability. Today, money doesn't just appear as cash — the development of Bitcoin and other cryptocurrencies ushered in a new phase in monetary history. These digital assets are based on cryptographic security, scarcity in code, and decentralized control by computer networks, not by states.
3. The 7 most important characteristics of money
For an asset to be accepted as money, it must have specific characteristics that make it functional, trustworthy and efficient:
3.1 Acceptance
Money must be generally recognized and accepted as a means of payment. Only when sellers, buyers, banks and the state regard it as a legitimate entity does the exchange work.
3.2 Divisibility
A key advantage of money is its divisibility. You can buy chewing gum with a coin or a car with a banknote — depending on the amount and combination. Digital currencies such as Bitcoin can be divided into up to 100 million parts (Satoshis).
3.3 Durability/Durability
In contrast to perishable goods such as fruit or meat, money must be durable. It must not rust, disintegrate, or wear out quickly. Paper money may be damaged but will be replaced with durable materials or digital copies.
3.4 Means of exchange
Money replaces the inefficient system of bartering. Instead of goods for goods, we now exchange for a universal means — money that is recognized almost everywhere.
3.5 Scarcity/limited quantity
If money was in abundance, it would lose value. That is why central banks regulate the money supply. With Bitcoin, the scarcity is defined in the code — there will ever be a maximum of 21 million units.
3.6 Transportability/portability
Money must be easy to carry — in your pocket, wallet or on an app. Whether in physical or digital form, portability is essential for daily use.
3.7 Uniformity/Fungibility
All units of the same value should be identical and interchangeable. Two 1 euro coins must have the same value and the same acceptance. This fungibility creates clarity and trust.
Additional criteria such as verifiability and protection against counterfeiting are essential so that no one can put counterfeit money into circulation unnoticed. Modern technologies such as watermarks, holograms or blockchain ensure that real money can be differentiated from counterfeits.
Functions of money: The 5 central roles
Economically speaking, money fulfills five elementary functions that are essential for the functioning of a modern economy:
3.1 Means of exchange
The primary role of money is that of a medium of exchange. It replaces direct barter transactions and enables efficient trade between millions of people.
3.2 Processing unit
Money can be used to specify prices and compare values. It serves as a measure of the economic value of goods and services.
3.3 Store of value
Money makes it possible to store purchasing power for the future. If it remains stable, it is also suitable as a long-term investment.
3.4 Means of payment
Whether rent, wages or loans — money is used to pay current obligations.
3.5 Asset storage
monies can be saved, invested and used for subsequent purchases — one of the most important prerequisites for economic planning and prosperity.
4. Comparing cash, fiat money and Bitcoin
Cash is the physical appearance of fiat money. It fulfills all important characteristics of money — it is divisible, transportable, relatively durable and above all: widely accepted. However, it is also vulnerable to inflation and manipulation by central banks if the money supply is increased too much.
Fiat money itself is based entirely on trust — in a country's economic stability, in its institutions, and in the government's ability to control the monetary system.
Bitcoin represents a radical alternative. It is digital, concise, decentralized and accessible worldwide. Its verifiability is ensured by blockchain technology, which guarantees maximum protection against forgery. Nevertheless, Bitcoin currently still lacks widespread acceptance, especially in everyday life — a point that has hampered its spread so far.
