What’s Bitcoin Really Worth?

What’s Bitcoin really worth? This question might really drive you mad if you think hard enough about it. $0? $10? Maybe $1,000,000 for one coin? The range of the numbers can make your head spin but it is the explanation behind the number that matters. For the most part, investors don’t have a good reason why Bitcoin is worth this or that, apart from claims that “it will take over the world” and so on. This hasn’t stopped people from trying, though. Is it even important for short-term traders? Can it boost profits on our hypothetical positions?

In an article on the Bloomberg Businessweek website, we have stumbled upon a number analyses of the value of the cryptocurrency. We read:

It took two economists one three-course meal and two bottles of wine to calculate the fair value of one Bitcoin: $200.

It took an extra day for them to realize they were one decimal place out: $20, they decided, was the right price for a virtual currency that was worth $1,200 a year ago, flirted with $20,000 in December, and is still around $8,000. Setting aside the fortunes lost on it this year, Bitcoin, by their calculation, is still overvalued, to the tune of about 40,000 percent. The pair named this the Côtes du Rhône theory, after the wine they were drinking.

If this sounds pretty definite, it actually isn’t. What the two economists used to value Bitcoin is called the quantity theory of money. Without getting too technical, it is a relatively simple equation which lets you recover the value of the currency. The caveat here is that this method is sensitive to the underlying assumptions and inputs. One of the crucial inputs is the value of what the currency buys and things go downhill from here pretty quick.

Does Bitcoin support $1.2 billion in payments? Or maybe it’s transmitting money from illegal activities and we should include this in the figure? Or it’s not that important what kind of resources Bitcoin transmits today but we should focus on what it will transmit in a year (two? three? ten?) and calculate what it’s value is going to be going forward? So, even though we do have an established model, the uncertainty about the critical input is a hindering factor.

Just how hindering is it? We could sugarcoat it, but we won’t. It’s simply too important a matter for Bitcoin investors and the hard facts are that the final value you get varies wildly depending on what input you use. For a static approach, where we focus on the current value of goods Bitcoin buys, a very conservative estimate would be the $20 for one Bitcoin we mentioned before. Different figures for what is bought for Bitcoin give answers like $600. This is still well below the current price. So, if you were to believe in the application of the quantity theory of money to Bitcoin, this would be a bearish implication.

Changing the approach from static to dynamic and assuming Bitcoin might actually become a safe haven the way gold is could give a target of $260,000 to $800,000. OK, by now you probably get the idea. Various principled approaches give results ranging from $20 to $800,000. If you consider different approaches, perhaps even more. What does this mean for you and your decisions?

The first clue is that if we don’t see any evidence of Bitcoin gaining more users and becoming a part of the fabric of the payments system or reacting strongly as a safe haven, then the currency might be trading too high.

The second one is that it is precisely the number of people willing to buy or sell Bitcoin that you have to observe. There are a lot of people who could potentially be interested in Bitcoin but don’t have access to it. It might be the case that the rally to the all-time high in Bitcoin was connected to the launch of first regulated Bitcoin derivatives. At the same time, one of the most striking characteristics of the Bitcoin market is that a vast majority of buyers has no concept of Bitcoin value altogether but ha simply bought the currency in the anticipation of a move up. With Bitcoin not going above the all-time high for some time now, these buyers might be shaken out of the market, fueling further declines. This is precisely the point where short-term considerations become important and so we’ll move on to the technical part of today’s analysis. In other words: for short-term positions, technical factors might be a lot more important that what Bitcoin is theoretically worth.
