The value of bitcoin

The total market value of all bitcoins is US$80bn, which is more than the value of Richemont and triple the value of Anglo American. It is the topic on which we currently receive the most questions from clients. In this article, Jacques Plaut discusses how we would apply our valuation techniques to virtual currencies, and whether we would own them for clients.

Before I say anything else, let me first say this: I do not know where the price of bitcoin is going. If you are looking for a price forecast, I’m afraid this is not the article for you. The best I can do is to tell you that it will fluctuate. Nonetheless, I hope that I will still be able to say some useful things about the value of bitcoin, and its suitability as an investment.

The problem comes in when people stop connecting the price of the asset to any underlying economic reality. If you believe the story, no price is too high.

Bitcoin is a virtual currency. In many ways it is like electronic Monopoly money, except the price is up 300 times in the past five years. At the time of writing you could exchange one bitcoin for US$5 200. Does this mean a bitcoin has intrinsic value of US$5 200? Is it really “worth” that amount? In one sense, yes: any asset is worth what you can sell it for. In another sense, no: market prices change – especially in the case of bitcoin – and at times bear no resemblance to intrinsic value.

One could say a bitcoin has zero intrinsic value, because ones and zeros on a computer, in isolation, have no use to anyone. But by the same argument a dollar also has zero intrinsic value. Unless you are like Scrooge McDuck, who gets joy from counting his money, a dollar is only valuable as long as someone will exchange it for some real-world good or service. The value of any currency is largely a matter of faith. But since I do not plan to talk in terms of loaves of bread, and since this is not a philosophy journal, I will speak of value relative to dollars for the sake of convenience.

Bitcoin as an asset

The usual methods for valuing an asset are not readily applicable here:

The present value of future cash flows: There are no future cash flows associated with bitcoin, except the price at which you will sell it one day. This price depends on the next selling price, etc.

Historical prices: The first bitcoin was traded in 2009. This is a short history compared with, say, the 150-year history we have for oil and the 2 000-year history we have for gold (which is the asset most similar to bitcoin). And the history we do have is not very stable.

Supply-demand analysis: The demand and the supply come mostly from speculators, and the attitude of speculators is notoriously hard to  foresee.

Relative scarcity: The ultimate supply of bitcoin is limited to 21 million coins. The supply of dollars is unlimited. Therefore, bitcoin should appreciate indefinitely against the dollar. The snag is that you could also apply this argument to property in Harare, or paintings by Sylvester Stallone. And while the supply of bitcoin is limited, the supply of virtual currency is not. There are at least 1 100 others, including Ethereum, Gnosis, Mysterium, and my favourite: PonziCoin. Some of these have better underlying technology than bitcoin.

Bitcoin as a currency

One could say that bitcoin is not an asset but a currency. Some even say that it will eventually become the world’s reserve currency. These people usually go on to explain that you need a monetary base of several trillion dollars for a global reserve currency. As mentioned, the supply of bitcoin is limited to 21 million coins. Several trillion divided by 21 million equals several hundred thousand, which is where the price of bitcoin is headed (they say).

First, I’m not sure that bitcoin will be the new reserve currency. The underlying technology is somewhat clunky and, like I mentioned, there is lots of competition from other virtual currencies. Also, people tend to value stability in their reserve currencies. One that is rapidly increasing in value will cause people to hoard it; one that is decreasing will cause people to spend. The current system of having a central bank that manages the stability of the currency by altering the supply of money, has worked quite well for a hundred years. Governments will presumably have a say in all this, and might not approve. It was illegal for US citizens to own gold from 1933 until 1975.

Second, I’m not sure the global reserve currency needs a monetary base of several trillion. At my church’s annual fair, you pay for everything with vouchers. If the supply of vouchers were too low, one possibility is that people would bid up the price of vouchers. But there are several other possibilities. People who run stalls could recycle their vouchers back into the pool more rapidly. Or people could write out IOUs: “I’ll pay you as soon as I get my hands on a voucher.” Or we could all go back to using rands. Money is, after all, a matter of convenience.

We normally value currencies by looking at the price history, the quality and track record of the issuing central bank, the amount of foreign reserves, the fundamentals of the sovereign, and the Big Mac Index. These are not easily applied to bitcoin.

The value of any currency is largely a matter of faith.


“There can be few fields of human endeavour in which history counts for so little as in the world of finance. Past experience, to the extent that it is part of memory at all, is dismissed as the primitive refuge of those who do not have the insight to appreciate the incredible wonders of the present.” – A Short History of Financial Euphoria, John Kenneth Galbraith.

Can behavioural psychology give us any insight into bitcoin?

The title of this section refers to “tulip mania” – an episode of frantic speculation on the price of tulips. It happened in Holland in 1637. There have been many similar episodes, involving Florida real estate (1926), gold (1980), Japanese assets (1990), and internet stocks (2000), to name a few. There is always some underlying justification, or “story”, at least at the start. Scarcity of bulbs, the Florida climate, gold’s virtue as an inflation hedge, the wisdom of Japanese policymakers, or the internet’s ability to change the world – these are the justifications that served for my examples above. The problem comes in when people stop connecting the price of the asset to any underlying economic reality. If you believe the story, no price is too high.

In the case of virtual currencies, the “story” which has captured the public imagination is blockchain technology. Blockchain technology is a way of enabling the digital transfer of money between two parties without an intermediary. The idea has lots of potential, and virtual currency is only one of many possible applications. But this does not make bitcoin worth anything, just like the existence of the internet was not enough to make a valuable asset.

I don’t know whether bitcoin deserves to be classed with episodes like tulip mania. I see some similarities with previous bubbles, but all the signs are not yet there. For example, the abuse of debt in some form is a standard feature of any bubble, and I’m not aware that people are using it to buy bitcoin, yet.

Three more things:

Would we own bitcoin for clients?

Regulations do not currently allow this for most of our funds. But regulations aside, we are always looking for good ways to preserve capital and earn returns for clients. We do not think bitcoin is an instrument which will enable us to do this. Indeed, we see material risk of capital loss.
