Bitcoin: An Unknowable Bubble?

Tyler Durden's picture

"Whatever [Bitcoin] is, I missed it... It looks and smells like all the bubbles I have seen throughout history." - billionaire investor Jim Rogers

Authored by Constantin Gurdgiev via True Economics blog,

There is a much-discussed in the crypto-sphere chart making rounds these days, plotting Bitcoin price dynamics against the historical bubbles of the past:

The chart is striking. Albeit simplistic. See Note 1 below for a technical argument on the chart timing.

On price dynamics alone, Bitcoin looks like a sure bubble - a disaster waiting to happen. But Bitcoin dynamics are basically not suited for any empirical analysis of any significant accuracy.

As noted by some commentators, Bitcoin had numerous 80-90% and larger drawdowns in the past (given its immense volatility). It keeps coming back from these. Some claim this to be the evidence that Bitcoin it not a bubble. Which is neither here nor there: bubbles are generated by exuberant expectations of investors, not by actual parameters of price processes. Causality does not flow from dynamics to bubbles, but the other way around. So to identify a bubble, one needs to identify exuberance. See Note 2 below for more on 80% drawdowns.

In the case of Bitcoin fans, there is clearly such.

No investor or serious analyst has been able to provide a fundamentals-based valuation model for Bitcoin.

A disclosure in order here: myself and a graduate student of mine have looked at the fundamental modelling for Bitcoin over the summer. We found no tangible relationship between any economic or financial parameters tested and Bitcoin price dynamics. In another piece of research, myself and two co-authors are currently looking at empirical dynamic and fractal properties of Bitcoin. Again, we finding nothing consistent with a behaviour of an asset with fundamentals-derived valuations.

Absence of evidence is not the same as evidence of absence. But, taken together with the general lack of credible fundamentals-linked modelling of the crypto-currency, this means that, at this point in time, Bitcoin price can be potentially driven solely by… err… expectations held by its enthusiasts, plus the incentives by the predominantly China-based investors to avoid extreme risks of capital controls and expropriations. If so, both drivers would make it a speculative bubble.

The only quasi-fundamentals-linked argument for Bitcoin has been the blockchain one - the promise of Bitcoin serving as a key tool for data aggregation, recording and transmission. This argument, however, no longer holds. Blockchain technology has migrated from public blockchains, like Bitcoin, to either open blockchains, like Ethereum or, increasingly more frequently, private blockchains. It is the latter that currently hold the promise to serve as viable platforms for data economy.

As a libertarian, I should like a private currency system that supports anonymity of transactions. As an economist, I should like the innovative nature of Bitcoin. And, put simply, I do. Both.

But as an investor, I do not have the stomach for Bitcoin’s valuations and volatility, as well as for its higher moments behaviour (in particular worrying are kurtosis, co-skews and co-kurtosis, which severely complicate empirical dynamics analysis, see Note 3 below). And I have even less enthusiasm for the crypto market that is sustained increasingly by undertakings, like BitMEX - a purely speculative platform trading some $35 billion in Bitcoin derivatives with leverage up to x100 to the amateur speculators who, put frankly, have zero idea what they are buying and at what price. The vast majority of Bitcoin investors have no clue what a butterfly option looks like and how it can be valued. And the vast majority of financial markets analysts and professionals won’t be able to price a butterfly strategy for Bitcoin, given its painfully twisted moments. Yet, within a month of starting trading, BitMEX reached 1/3 of the market capitalisation of Bitcoin. This is not just a shoe-shine-boy moment, folks. It is white-powder-under-the-nose-and--empty-bottles-of-vodka-on-the-floor hour for high school dropouts with cash to burn.

Another worrying issue with Bitcoin is the argumentation of its main supporters.

This ranges from the cognitively biased “you don’t know anything about the Bitcoin” to “Bitcoin is scarce & limited in supply” to “Bitcoin is a promise of liberating the masses from the oppression of the Central Bankers”.

The first sort of argument exhibits not just Jurassic ignorance of logic, but also a gargantuan dose of arrogance. Repeated sufficiently enough, it signifies the absurd degree of exuberance of investors’ expectations.

The second argument is patently false. Bitcoin has undergone splits, and engendered dozens of other cryptos, with unlimited supply of such into the future. Bitcoin itself is divisible ad infinitum and, with forks, its supply is potentially unlimited. Worse, Bitcoin rests on man-made mathematical foundations. Which means it has no physical bound or constraint. Anything man-made (and even more so, anything mathematically derived) is, by definition, fungible and axiomatic. Just because to-date no one cracked the code to alter Bitcoin mid-stream or drain blockchain-held information does not mean that in the future such a code cannot be written. So hold your horses: gold is physically limited in quantity (even though in the Universe, it is not as scarce as it is on Earth, which makes long term supply constraint on gold potentially non-binding). Bitcoin is limited by our capacity to alter the underlying code defining it. Anyone thinking of an algorithm as a 'law' needs to go back to Godel's mathematics.

Finally, there is an argument of ‘liberation’. Bitcoin value is only sustained as long as it remains convertible into goods, services and other currencies. This means that Bitcoin cannot remain a government- regulation-free asset, as long as its popularity as a medium of exchange and a vehicle for store of value grows. Which means that in the medium terms (3 years or so?), Bitcoin will either cease to be, or cease to be anonymous. All protection from the dictate of the Central Bankers will be gone.  Benign tolerance of Bitcoin by some regulators can quickly turn into outright prohibition on trading - as current and past examples of China, Vietnam, Nigeria, Colombia, Taiwan, Ecuador, Bangladesh, Kyrgyzstan and Bolivia, Russia, and Thailand suggest. Evolution of cybersecurity measures and regulatory and supervisory tools, including their spread into cryptocurrencies domain will only increase effectiveness of such measures into the future. So, unless you are planning to live in a libertarian paradise, where legal norms of other states do not apply, good luck committing much of your wealth to Bitcoin as a safe haven for oppressive or coercive actions of the nation states.

Worse, anyone claiming that Bitcoin is a hedge against inflation fails to understand how modern markets work. Again, to increase in value, Bitcoin requires higher rates of adoption. Higher rates of adoption bring about higher rates of asset instrumentation (see above for BitMIX). Higher rates of instrumentation and adoption, taken together, imply higher holdings of Bitcoin by institutional and diversified portfolio investors. So far so good? Right, now the kicker: these holdings imply greater, not lower, positive correlations between Bitcoin and other asset classes in shock-experiencing markets. That's right, dodos: Goldman holdings of Bitcoin are correlated to liquidity supply in general markets, because if such liquidity starts evaporating, Goldman will sell Bitcoin to plug holes in other instruments. Sell-off in the markets can trigger sell-off in Bitcoin. Now, another kicker: Bitcoin is currently less liquid than any major asset class (see extreme volatility of pricing across various Bitcoin exchanges). Which means that smart folks at Goldman will be dumping Bitcoin before they dump gold and other assets. Hipsters hugging their laptops will be the last to wake up to this momentum (behavioural evidence suggests, they might actually buy into falling Bitcoin in hope of speculatively gaining on a bounce, which, incidentally, can explain why large drawdowns in Bitcoin can turn so fast into upward trends).

The tricky bit about Bitcoin is that its enthusiasts need to learn to live in the real world first. Until they do, Bitcoin will continue its upward path, and this process can go one for quite a while, depending on the supply of cash in the markets for Bitcoin. Once they are taught a sufficient lesson, however, the rest of us will be learning the long term fundamentals valuations of Bitcoin. I, for now, have no idea what these valuations might be.

So Bitcoin, then. A bubble or not?

If you ignore the arguments that attempt to justify its valuations, it looks like one, albeit with dynamics that are very hard to interpret.


If you listen to them, it looks that way even more, with more confidence in the arguments bogus nature.

Draw your own final conclusions.

*  *  *

Note 1: In defence of the chart above, without validating its implied conclusions: the chart plots Bitcoin evolution from 3 years ago through today. This starting point makes sense. Until mid-2014, Bitcoin was extremely obscure, hype-only investor vehicle, with volatility so off the charts, any analysis of its dynamics was futile (I know, I did such analysis and presented the results in my talk at Bloomberg two years ago). Those us who do research in finance generally and routinely disregard the first 3-4 years of existence of Bitcoin for exactly that reason.

Note 2:  A note due here: Bitcoin's returns from 80-90% drawdowns is not a solid evidence of the crypto-currency not being a bubble, because they are in line with Bitcoins' overall massive volatility. In other words, a valid comparative for these drawdowns relative to other asset classes is not "an 80% drawdown in  Bitcoin ~ an 80% drawdown in stocks", but "an 80% drawdown in Bitcoin ~ an 8% drawdown in stocks". Apples to apples. Dust to dust.

 Note 3:  Interesting Elliott Wave analysis of Bitcoin dynamics here and here , although I am not convinced Bitcoin price trends are established enough for this technique to work.

Bubbles everywhere......

Satoshi Nakamoto only coded tangible and inherent value into his supreme digital wealth creator.  He specifically did not add any bubble to his divine code!

For all of you riding high on the BTC Titanic, I say, congratulations!  My only advice is that you jump ship before it hits the iceberg and founders.

Looks like the Tether pumps have stopped as Bitfinex has been called out on it and is being watched very closely.

Expect a correction to follow shortly unless one of the rich people predicting 10k+ by end 2017 decides to pump it themselves to avoid being wrong.

tmosley's picture

I wouldn't bet on that. Plenty of longer breaks on the chart.

That said, BCH is pumping this morning.

Gaius Frakkin' Baltar's picture

Goldbugs can't offer any viable alternative, just laments.

Show us an alternative that works in the modern world. We're suppose to believe Gold is the only non-governmental currency that will ever work?

The Dotcom bubble supposedly popped 17 years ago and here we are talking about FANG stawks.

Gotta love the ad hominem here. Anyone who presents a fundamentals based valuation for crypto is not a serious analyst, apparently.

Yes, crypto will take over the role of broad money and probably debtmoney AND equity in the economy. That thesis produces astronomical valuations that the author simply doesn't want to consider, so he dismisses those proposing it as "not serious".

Well, we're half fucking way there.

If The Bitcoinerz were smart, they would back Bitcoinz with Physical~~~ 1 ozs GOLD, 100 ozs SILVER and 500 lbs of Copper ...

Bitcoinz would have eternal intrinsic value, and it would never collapse back to ZERO !

It would also TRUMP all Paper Fiats on this planet ...

What is interesting on that chart is that Tulip Bulbs went to a 50 multiple and the Bitcon is less than a 40 multiple at this point.


JimmyJones's picture

All currencies have lost buying power, all have depreciated together, except for the Crypto's.  Just saying.  Anyhow not owning any is just retarded in my opinion, own some stocks, some physical gold/Silver and some Crypto.  Also invest in yourself via applicable skills that others need.

"All currencies have lost buying powe... except for the Crypto's."


Because, fun-durr-mentals... with an emphasis on mental.

JimmyJones's picture

Can't prove me wrong huh?  Cut Bit coin in half, it still is better.

ThirdWorldDude's picture

Does cutting a two bit coin (sic!) in half involve sheering scissors?

Raffie's picture

PM prices are suppressed, manipulated and paper gold rules over physical in the markets where this would be.

So back Bitcoin backed with paper gold is what you are saying correct? 

What could possible go wrong.  


ZH Snob's picture

it will become backed by silver and gold when the fiat currencies reach their intrinsic value of 0.

at that point, you won't want the 20k dollars they say your gold is worth.  you will want the crypto that maintains its value of however much silver or gold it sells for, knowing that it is not fiat in nature, that it has a limit of issuance.

I'm not an anti crypto guy.  I think people should spend their mining time and money whereever they like...

...but I do like the “Bitcoin is scarce & limited in supply” arguement.  which to NOT an arguement.  Any arguement that make a crypto case identical to the case for my own not a great arguement.

tmosley's picture

Scarcity and limitation of new issuance are features that speak to the distribution of the market capitalization, not the market capitalization itself. Scarcity isn't the only thing that gives cryptos value/purchasing power.

The power to be your own bank is NOT granted by your shit.

How can we have a bubble mania discussion without including Chinese Real Estate!!   "Homes" selling at 50x average annual incomes in geographical locations throughout China....oh, and, you don't really get to "own it" anyway.

roddy6667's picture

Most people in most cities in China can afford the homes. Most pay cash. And there is no property tax. In America, you have to pay a tax to the owner of the land or they send men with guns to kick you off it.  Nobody in America owns land. The government owns it all.

Your consciousness isn't tangible, but I bet it's worth something to you.

If it wasn't for humanity, particularly White men, you'd be in sorry shape and so would I.

If you're going to start trading your conscious thoughts on an exchange you should probably offer that one at a deep discount.

The only real wealth is your health and your capacity to help yourself in case of crisis.

Nobody will ever do this for you, unless you're ready to give up something of value or make a sacrifice commensurate with your holdings.

And obviously this is your value proposition, and people who seek will find you soon or late.

Gaius Frakkin' Baltar's picture

All wealth is derived from people. This is something many Goldbugs fail to understand. There's something not right with them. There's something not right in their heads.

There is something not right letting them live in yours, stupid battle to choose.

^^ This.

Real estate is still here and still making money too, despite the number of "bubbles" it's been in.. Just because it's a "bubble" right now doesn't mean it doesn't have long term legs. If you're in it long and you bought (very) low, who gives a shit. BTC is here to stay as are lots of the best cryptos. BTC probably won't be the "winner" but again, who cares..

Look, another progressive trying to explain away history's lessons!!

Grave's picture

and this "genius" claims:
"gold is physically limited in quantity"
apparently has no idea you can actually create gold (for example using particle accelerators)

just like you can create diamonds

it takes more energy than its worth though at this time, get a "free unlimited" energy source and poof you can make as much gold as you want.

malek's picture

Yeah around 10^23 atoms per ounce of gold

sounds like a plan

This is perfectly normal when the goal is to extract wealth from the ignoramus.

You'd better blow off their 7 seconds attention span and make their head spin in all directions.

Mining has become very very expensive, but thankfully these forks in the BTC blockchain scattered the load and made it possible for big miners with huge antiquated farms to stay in global warmong business for a little longer.  Hobbyists as well can now get their old miners out of storage and kick them off again.

So, were these forks organized for this purpose?




JimmyJones's picture

That is not true, Miniing via old equipment is viable again only because the price of Bitcoin increased making it worth it becasue the price increase out paced the increased diffuculty level of mining them (as more are mined the diffuculty increases so it takes more time to mine them with old equipment).  If the valuation goes down then they aren't efficient enought for it to be cost effective.  It's not worth buying a prebuilt mining rig, it is worth building one yourself, if you know how.

yardsale's picture

Good point. Had to think they couldn’t scale their tech to mine efficiently, so peeled off a new flavor with easier mining. BTG is same. Recent thread on bitcointalk mentioning mining plan to switch from btc to bch enmass once btc difficulty increases next week, leaving all BTC transactions and coins effectively frozen, due to the lack of hashing power and increased mining difficulty.

Yeah, noone should buy BCH now.

Etiher some big announcement will be made (thus, insider trading is happening already), or just a regular pump to keep the price around 1,100 EUR.

Considering that it started happening some 2-3 hours ago (middle of EU TZ), and how it floats around 1,100 EUR - probably someone from Europe fucking around.

I can't figure out if there is a way to figure out trade volumes, on various exchanges, per currency, per hour of the day. shows 24h totals, wonder if it's possible to get hourly breakdown somewhere else. Or maybe I am expecting too much.

tmosley's picture

Go to binance and use their interactive charts. It's pretty handy.

MANvsMACHINE's picture

The move in BCH this morning might have something to do with the Difficult Adjustment coming to BTC this weekend. Could be the beginning of the 'flippening' so traders may be hedging. If true, I expect BCH to continue marching higher into the weekend.

blentus's picture

Actually, the opposite has happened, something noone expected.

  1. Individual users can now access USD wires for deposits and withdrawals
  2. Euro wires added for both corporate and individual accounts
  3. First Euro trading pair, /t/BTC:EUR, now live.

Bitfinex is, apparently, handling incoming wire deposits again, publicly.

Apparently, they were already providing ('beta testing', I guess - but I am presuming that just didn't want to get a small shitty Polish local bank into headlines, heh) this service to really big players, so it might be entirely possible that some of those $670,000,000 did not just come out of a thin air.

Yesterday, I sent some BTC, exchanged to IOTA, sent it back to my wallet - everything was reasonably fast (~15 minutes for IOTA transfer, but I don't have 2FA setup, and they warn that it takes longer).

I had a feeling they'd be dead by yesterday/today, but they are still kicking, for now.

OpenThePodBayDoorHAL's picture

LOL "15 minutes to transfer" but "it's the great new internet money". LOL

Buckaroo Banzai's picture

bank wires take 24 hours to transfer. 15 minutes is pretty darn good by that standard. Did it ever occur to you that BitCoin can be very successful without having to be the cryptocoin of daily low-value transactions?

People are so used to being forced to transact in only one currency per political jurisdiction, that they can't conceive of a reality where they can choose amongst dozens of different currencies to transact in every day. Future generations will look back at that antiquated notion, and laugh.

Unlike the tulip buble, the bitcoin mania is developing on the global stage. It will eventually lead to a bubble, but the price apprecition still has a long way to run.
