Fortunately, the Financial Times has been doing its usual first-rate job poking at the bubble. Here Jemima Kelly explains how meaningless the standard Bitcoin narrative is. The whole piece is highly recommended as is the HODL link and Trolly's blog.
The first problem is that bitcoin is not of course a company — nor even, we would argue, an asset — so working out its “market cap” is a non-starter. As some of you might remember, it was originally designed to be a currency that could be used to buy actual things! And although it fails to meet all the criteria that would make it a currency, it does have one thing in common with it: its price is underpinned by sheer faith. The difference being that with fiat currencies, that faith is effectively placed in the governments of the nation states who issue them, whereas for bitcoin, the faith is placed in . . . the hope that other people will keep having the faith. A faith in faith, if you will.
Another problem is that although 18.6m bitcoins have indeed been mined, far fewer can actually be said to be “in circulation” in any meaningful way.
For a start, it is estimated that about 20 per cent of bitcoins have been lost in various ways, never to be recovered. Then there are the so-called “whales” that hold most of the bitcoin, whose dominance of the market has risen in recent months. The top 2.8 per cent of bitcoin addresses now control 95 per cent of the supply (including many that haven’t moved any bitcoin for the past half-decade), and more than 63 per cent of the bitcoin supply hasn’t been moved for the past year, according to recent estimates.
What all this means is that real liquidity — the actual available supply of bitcoin — is very low indeed. That’s quite obvious even without knowing the stats above from the price moves — you don’t see smooth ups and downs like you might expect in other markets where the demand is coming from real supply-and-demand dynamics rather than speculation, but sudden lurches upwards and cliff-like drops.
So the idea that you can get out of your bitcoin position at any time and the market will stay intact is frankly a nonsense. And that’s why the bitcoin religion’s “HODL” mantra is so important to be upheld, of course.
Because if people start to sell, bad things might happen! And they sometimes do. The excellent crypto critic Trolly McTrollface (not his real name, if you’re curious) pointed out on Twitter that on Saturday a sale of just 150 bitcoin resulted in a 10 per cent drop in the price. As Trolly said to us over the phone:
If you can destroy the market like that in the space of seven or eight minutes, that shows there is no liquidity and no depth — nobody is there to take the other side of the trade when things start moving. You have these extreme moves because everyone is on the same side.
More than 2,000 wallets contain over 1,000 bitcoin in them. What would happen to the price if just one of those tried to unload their coins on to the market at once? It wouldn’t be pretty, we would wager.
What we call the “bitcoin price” is in fact only the price of the very small number of bitcoins that wash around the retail market, and doesn’t represent the price that 18.6m bitcoins would actually be worth, even if they were all actually available.
So the “market cap” is in this way nonsense multiplied. You times two things together that don’t reflect what they claim to — the “circulating supply” and the “price” — and voilà!
