In this post I address issues of competing government currencies, competing private currencies, gold, silver, bitcoin and alternative “crypto-currencies”.
We all know that variety and competion is a good thing. We all want slightly different things, value the same things differently or make different trade-offs. That’s why we have a wide variety of products, prices, quality, colors and materials on the market. Interestingly, money is different. We all want one single universal money. It may not be obvious to many people, so let me explain.
How money is different from everything else? On one hand, money is just an asset. You can produce, buy, sell or hold it. On the other hand, money is a medium of exchange. It allows you to trade your 8 hours in the office for a new iPhone. It also allows you to delay consumption decision. You can spend 8 hours of work today, but then be free to decide when and for what to spend your salary. If suddenly you need to buy a ticket to Hong Kong, you can do it without working extra couple of hours to earn it.
