The value of bitcoin

2017-11-23 11:36

The total market value of all bitcoins is $130 billion (around R1.8 trillion), which is more than the value of Richemont and triple the value of Anglo American.

Bitcoin is a virtual currency. In many ways it is like electronic monopoly money, except the price has gone up at least 300 times in the past five years.

At the time of writing, you could exchange one bitcoin for over $7 800 (or R109 552).

Does this mean a bitcoin has an intrinsic value of $7 800? 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, are 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.

. 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.

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 sell or 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 1934 until 1975.

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.

TULIP MANIA

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, such as Florida real estate (1926); gold (1980); Japanese assets (1990); and internet stocks (2000), just to name a few.

There is always some underlying justification, or “story”, at least at the start.

For the above examples, these justifications included: Scarcity of tulip 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.

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” that 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 Pets.com 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

1. Bitcoin is not a friend of the environment.

According to one estimate, the total amount of electricity consumed by processing bitcoin transactions is enough to power 1.6 million US households for a year.

Bitcoin uses more electricity than Lebanon or Cuba.

2. Some blame central banks for the rise of virtual currencies. Because the US Federal Reserve is keeping rates low and printing money, they say, people are putting their faith in other assets.

I’m sceptical of this explanation.

Bubbles can happen in any interest rate environment. When the price of gold peaked in 1980, US interest rates were 14%.

3. The idea of an alternative currency is not a new thing.

Before Lincoln signed the National Banking Act of 1863, the US had hundreds of currencies, issued by individual banks.

They were often backed, to varying extents, by gold. Those that weren’t tended to end in collapse.

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.
