The origin of money can be traced back to the evolution of barter trade and the human desire for collectibles. Barter trade, while useful in small communities, became inefficient when it came to larger groups and long-distance trade, leading to the development of a more efficient means of exchange known as "proto-money." Proto-money were collectible items that served as a store of value and enabled trade. As humans evolved, they developed the ability to anticipate future demand for certain collectibles, giving them an advantage in completing trades and acquiring wealth.
The adoption of a single store of value, known as a Nash Equilibrium, greatly facilitated trade and the division of labor, paving the way for the advent of civilization. Achieving this equilibrium can be difficult, but once it is established, it can greatly benefit society. Gold became the dominant store of value in the 19th century, leading to an explosion of global trade and economic progress.
However, the current structure of money is potentially changing with the rise of digital currencies and blockchain technology. Digital currencies offer several advantages over traditional currencies, including faster transaction speeds, lower transaction costs, and increased security. Additionally, the use of blockchain technology allows for the creation of decentralized systems that can enable trustless transactions without the need for intermediaries.
The widespread adoption of digital currencies and the development of new financial systems based on blockchain technology is not without its challenges. Concerns have been raised about the environmental impact of digital currencies, as the mining process required to create new coins can be energy-intensive. There are also concerns about the potential for digital currencies to facilitate illegal activities, as they can be difficult to track and regulate.
As technology continues to evolve and societies become increasingly interconnected, the future of money is uncertain. However, the convergence on a single store of value has historically facilitated trade and paved the way for the advent of civilization. It remains to be seen how the changing structure of money will impact global trade and economic progress in the coming years. The challenge for society will be to find a balance between innovation and regulation to create an efficient, secure, and sustainable financial system.
Durability: Comparing Gold, Fiat Currency, and Bitcoin
Durability is one of the primary attributes that people consider when storing value in a particular asset. In this regard, gold, fiat currency, and Bitcoin differ in their levels of durability. Gold has been recognized as a store of value for thousands of years, with the vast majority of gold mined or minted still in existence today. Even gold coins used as currency in ancient times hold significant value today. Fiat currencies and Bitcoins, on the other hand, differ from gold in their level of durability because their value depends on the institutions that issue and secure them.
Fiat currencies are fundamentally digital records that can take physical forms such as paper bills. The durability of fiat currencies is dependent on the longevity of the institutions that issue them. Over the centuries, many governments have come and gone, and their currencies disappeared with them. For example, the Papiermark, Rentenmark, and Reichsmark of the Weimar Republic no longer have value because the institution that issued them no longer exists. History has shown that it would be unwise to consider fiat currencies durable in the long term, as the US dollar and British Pound are relative anomalies in this regard.
Similarly, the durability of Bitcoin is reliant on the network that secures them. Since Bitcoin has no issuing authority, it can be considered durable as long as the network remains in place. The network has continued to function despite notable instances of nation-states attempting to regulate Bitcoin and years of attacks by hackers, displaying a remarkable degree of anti-fragility. However, Bitcoin is still in its infancy, and it is too early to draw strong conclusions about its durability.
Portability: Comparing Gold, Fiat Currency, and Bitcoin
Portability is another essential attribute to consider when storing value in an asset. Bitcoins are the most portable store of value ever used by man. Private keys representing hundreds of millions of dollars can be stored on a tiny USB drive and easily carried anywhere. Furthermore, equally valuable sums can be transmitted between people on opposite ends of the earth nearly instantly. Fiat currencies, being fundamentally digital, are also highly portable. However, government regulations and capital controls mean that large transfers of value usually take days or may not be possible at all. Cash can be used to avoid capital controls, but then the risk of storage and the cost of transportation becomes significant.
Gold, being physical in form and incredibly dense, is the least portable. Transmitting physical gold across large distances is costly, risky, and time-consuming. It is no wonder that the majority of bullion is never transported. When bullion is transferred between a buyer and a seller, it is typically only the title to the gold that is transferred, not the physical bullion itself.
Fungibility: Comparing Gold, Fiat Currency, and Bitcoin
Fungibility refers to the ease with which one unit of an asset can be exchanged for another unit of the same asset. Gold provides the standard for fungibility, as when melted down, an ounce of gold is essentially indistinguishable from any other ounce, and gold has always traded this way on the market. Fiat currencies, on the other hand, are only as fungible as the issuing institutions allow them to be. While it may be the case that a fiat banknote is usually treated like any other by merchants accepting them, there are instances where large-denomination notes have been treated differently from small ones. For example, the Indian government, in an attempt to stamp out India's untaxed gray market, completely demonetized their 500 and 1000 rupee banknotes. The demonetization caused 500 and 1000 rupee notes to trade at a discount to their face value, making them no longer truly fungible with their lower denomination sibling notes.
