A Bitcoin flash crash

Bitcoin has been on a sharp course downwards for a few weeks now (chart courtesy of Bitstamp).

But on Monday, the unthinkable happened.

Bitcoin prices on the BTC-e exchange suffered a flash crash that took the price as low as $309 per bitcoin from a day high of $497.79.

Here’s the damage:

Newsflash Bitcoin people, we already have a private money system

The following from Paul McCulley, chief economist at Pimco and Zoltan Pozsar, a senior adviser at the US Treasury department, came out earlier this week in the FT, but is worth rehashing in light of this relatively absurd call from the Institute of Economic Affairs for the UK government to privatise the pound and replace it with Bitcoin (capital B).

The central message of the McCulley piece being — one which happens to be echoed by most seasoned central bankers and economists — that we do of course already have a private money system! And that was part of the whole problem!! Read more

Blockchains vs stock exchanges

Since we just spent a good while arguing against the idea of blockchain society, we thought we’d quickly follow up with a post explaining why that doesn’t necessarily mean we’re against blockchain innovation itself.

It’s very likely that the blockchain might one day be usefully incorporated into existing services to make them better and fairer. We’re just not convinced this will necessarily democratise the world the way Matthew Sparkes at the Telegraph envisions or make it cheaper to process information. If anything, it’s likely to de-risk markets (the sort that feature real goods and services) through improved information gathering, sharing and transparency — something which limits the need for currencies, not increases it. Read more

I see blockchains

The Telegraph’s Matthew Sparkes, just like Neo in the Matrix, has fallen down the blockchain rabbit hole. Everywhere he looks he sees blockchains.

Blockchains for automated self-driving car-fleet management. Blockchains for money. Blockchains for stock. Blockchains for votes. It’s cybernetic blockchain utopia!

Or as he puts it: Read more

Who’d have thought. Cryptocurrencies are replicating conventional systems

We were struck by a PR email we received this week directing our attention to a three-month old crypto currency called “Blackcoin”.

According to said PR:

… [Blackcoin] is already one of the top 10 by market cap. BlackCoin is based on many of the ideas contained in the original Bitcoin protocol, but with a few important changes. Most critically, BlackCoin secures its network entirely through Proof of Stake, compared to Bitcoin, which uses Proof of Work.

Okay, we’ll play. Please tell us more about this revelatory innovation called “proof of stake”? Read more

Bitcoin shocker!

Here’s one for the FT Alphaville Blockchain log.

It seems key bitcoin foundation member Gavin Andresen has finally figured out that the cryptocurrency’s competitive transaction fee may be dependent on a constant capital transfer from real money systems.

And, more specifically, that when people stop subsidising miners with “seigniorage” revenue, they’ll either have to:

1) Hike fees to compensate miners for managing the currency and not bailing out. [Surely you mean interest rates? - Ed]

2) Make the thing much less costly to run by making the hash rate easier, something which would inevitably expand the money supply. Read more

Why the golden goose market may be decaying

That Isaac Newton, one of the greatest minds that ever lived, was both mathematician and physicist and alchemist and gold standard enthusiast seems in the context of the bitcoin movement oddly appropriate.

After all, nothing represents the fusing of mystical alchemical forces with the principals of physics and maths better than a crypto-currency — especially when its supply is designed to be purposefully rigid, like gold.

Nowhere is that fact more evident than in the market for crypto-currency mining rigs. Read more

Peak Bitcoin or peak hedge fund?

Tim Hartford directs us to a nice piece by John Cassidy in the New Yorker this week wondering why it is that hedge funds can still get away with making a killing when their performance is so underwhelming these days.

It is, in his opinion, a bit of a mystery.

He adds that even though institutional money is putting pressure on fees — in some cases leading to the traditional 2 and 20 model being sliced to 1.4 and 17 — it’s hardly enough of a cut to justify the lackluster performance.

Furthermore, the biggest and most successful funds don’t seem to have this problem. Their ability to attract money on those terms suggests there’s no end of rich people happy to throw their money at them. Read more

The linguistic verdict: Dorian is probably not Satoshi

Everyone has a linguistic signature (apparently).

Luckily for Bitcoin sleuths trying to determine the real identity of Satoshi Nakamoto the existence of *that* Bitcoin white paper provides everyone with some valuable clues. Read more


We referenced the obvious similarities between the oil market and the Bitcoin market — specifically with regards to cost of production and capital intensity preventing a competitive threat to Opec — in our previous post.

In a fortunate coincidence, John Kemp at Reuters today directs his readers to the myth-busting 2004 work of former MIT professor Morris Adelman, who compellingly argued against the “oil is running out, prices can only go up” thesis. Read more

Let them eat Bitcoin mining rigs

Bitcoin prices are in retreat, seeming to suffer from the triple whammy of a Chinese crackdown, ongoing repercussions of the MT.Gox implosion as well as the IRS deciding that miners will not be immune to tax in the US.

If you view Bitcoin as a high-risk tech investment, the price might also be reflecting wider tech rot as well. Read more

Standing on the shoulders of cryptocurrency giants

Dorian Satoshi Nakamoto, the LA-based man that Newsweek alleged on Thursday was the probable creator of the Bitcoin protocol, denied all involved in an AP interview — but the plot continues to thicken.

As the International Business Times reports on Friday, an online chat account associated with the email featured in the original Bitcoin white paper has become active again.

Surprise, surprise — the user is claiming that the man featured in the Newsweek article is not Satoshi Nakamoto.

At this stage, one has to ask what’s really preventing the real Satoshi from revealing his true identity and claiming his fortune? (And there are reports that the bitcoins associated with Satoshi are already on the move on Friday.) Read more

Magic: the undercapitalised gathering online

Tech billionaire and bitcoin investor Marc Andreessen says Mt Gox is to bitcoin what MF Global is to the dollar.

We disagree.

But before we get to that, we’d like to explore revelations that it may not have been a malleability issue, a.k.a. a transaction doppelganging problem, that brought down the world’s premier bitcoin exchange but the much more common problem of “under-capitalisation”. It’s a common problem of banks and ponzi schemes everywhere. Read more

The Bitcoin personality cult lives on

How to handle bad news, by public relations guru and propaganda expert Edward Bernays from his book Propaganda (1928):

The counsel on public relations must be in a position to deal effectively with rumours and suspicions, attempting to stop them at their source, counteracting them promptly with correct or more complete information through channels which will be most effective, or best of all establish such relationships of confidence in the concern’s integrity that rumours and suspicions will have no opportunity to take root.


A single factory, potentially capable of supplying a whole continent with its particular product, cannot afford to wait until the public asks for its product; it must maintain constant touch, through advertising and propaganda, with the vast public in order to assure itself the continuous demand which alone will make its costly plant profitable.

Some altcoin memes are more equal than others

Bitcoin may be many things: a cheaper and more efficient payments mechanism, a decentralised form of QE, an extreme way to break through the ZLB, a worthy private substitute for cash, an opportunity to stick it to the man or even a speculative investment opportunity of a lifetime.

What it isn’t, however, is a fair distribution of income.

Steven Englander at Citi comes to a similar conclusion, despite previously appearing a tad more enthusiastic about the idea of a private currency gaining traction. Read more

Breaking through the ZLB with virtual currencies

Here’s a crazy thought to start the New Year year with. What if virtual currencies were born less of an organic anti-government peoples’ movement and more of extreme unconventional monetary policy by the state? The ultimate central bank Jedi mind trick if you will, which takes easing to levels that conventional policy just cannot go.

But even if it’s not a plan hatched directly by monetary bodies to serve the interests of the state, there’s still a strong argument to be made that virtual currencies could be doing the Fed, the BoE and even the ECB a big favour. Read more

The Hubble bubble theory of the continuous expansion of the financial universe

Or something like it. We’re not, after all, physicists. Though, feel free to read about the Hubble Bubble theory here. What we probably should be referring to is Hubble’s flow, the rate at which expansion of the universe occurs.

All of which is a whimsical way of suggesting that perhaps Larry Summers has a point. Perhaps bubbles are part of our collective universal nature? A phenomenon that should be embraced as an unstoppable physical force, one that will find a way no matter what.

The proof is out there if we look hard enough. Latest manifestation: Bitcoin.

If we go with that notion, then perhaps inflating asset bubbles one after the other isn’t such a bad idea. Perhaps it’s even necessary? Read more

There’s nothing new under the sun, including Bitcoin

Capital controls, Bitcoin edition

An interesting thing happened on the way to Sheep Marketplace — the online market for illicit goods which rose to prominence after Silk Road, the dominant site for illicit goods trading, was apprehended by the Feds in October.

The interesting thing is not that after a couple of months in the limelight the site closed down because a hacker allegedly made off with $5m worth of Bitcoins. Nor is it that the Bitcoin community failed to buy the story because they noticed that all withdrawals from the site were being blocked by the site’s operators — promptly branding the entire website a scam from the beginning.

What is interesting are the “capital controls” the community is now effectively enforcing on the Bitcoin wallet address they suspect is responsible for the theft. In fact, an entire community of Bitcoin vigilantes has sprung up on the Reddit website, dedicating themselves to chasing the money across the open peer-based Bitcoin ledger. Read more

So this is how fiat currency dies, with thunderous CPUs?

We noted that the shift from Bitcoin into other crypto alternatives, which give early adopters a better chance at pilfering wealth from suckers, had already begun.

We referred, for example, to the rise in Litecoin. But this was foolish. We were thinking too small. There are so many other virtual choices on the market. Read more

The Litecoin disruption

When things get too expensive, imperfect substitutes become increasingly appealing.

It happened to oil with natgas and shale. It happened to gold with copper and silver. Now it seems to be happening with Bitcoin as well.

So while Bitcoin traded through $1,000 on Wednesday (depending on which exchange or service you use to acquire Bitcoin: it was $1,035 on MTGox, $922 on BTC-e at pixel time), more interesting is the recent surge that’s taking place in the value of alternative crypto currency Litecoin: Read more
