Four days ago, Bitcoin was under $2 USD. Now it's over $4 USD (depending on when you refresh the page). There are 6 million bitcoins in existence, and trade volume is only about 54,000 according to the biggest exchange. There aren't enough bids/asks to soak up more than about $100 USD without throwing the exchange rate one direction or the other.
For example, right now (as I write this) exchanging $1000 USD for some Bitcoins is all it takes to push the exchange rate up $0.10 from $3.77 to $3.87.
What a lot of Bitcoin newcomers don't realize is that Bitcoin depends on 'mining' to generate new bitcoins. Computers run cryptographic hashes to find the 'winning' has which is less than the current difficulty target number. The computer that finds this hash is awarded 50 BTC. The difficulty target is automatically adjusted upward to keep new bitcoin generation at a constant pace.
Some quick research shows a handful of big players in the mining market who have invested heavily in high-end GPUs for dedicated bitcoin mining, some with over 50 GPUs running 24/7 for months now. These guys are bound to have huge quantities of bitcoin they are eager to unload when the price is right. Meanwhile, news coverage is driving exploding popularity, which appears to be pulling the exchange rate sky high. On paper, many of these guys have become overnight millionaires just by running a bunch of computers 24/7.
Of course, as these players cash out the exchange rate will fall. These guys are too smart to sell all at once and flood the market, but with volatility like this I'm willing to bet a lot are eager to pull their bitcoin out of the game before the bubble pops.
Meanwhile, hardware enthusiasts all over the internet are rushing to buy GPUs to dedicate to mining. They don't seem to realize that the bitcoin system automatically adjusts to keep the bitcoin generation rate constant at 50 BTC per 10 minutes. As the mining market becomes flooded with new 'miners' the difficulty will climb rapidly, until it becomes unprofitable to run a GPU if you have to pay for electricity.
Finally, bitcoin is highly illiquid. My research was brief, but I couldn't find an easy way to exchange small amounts of BTC for USD that didn't look terribly sketchy or involve a lot of fees. Stores aren't eager to accept bitcoin because the exchange rate at the moment can easily swing 10% between when the user presses 'check out' and the transaction is processed.
The bitcoin system is a very interesting concept, and it was clearly implemented by some very intelligent people. But as it currently stands it's just a playground for speculators and market manipulators. Expect some carnage in the coming months.
As a bitcoin veteran, I expect carnage, always. I learn that the hard way several months ago.
Moreover, I tend to be fatalistic about the price of bitcoin. Whether or not the market is manipulated, as long goods and services are popping up in the bitcoin economy, we'll be alright in the long run.
Mining is supposed to fade away in importance - it was just a way to bootstrap. And huge computing power applied to mining means that it's so much harder for a hostile entity (hello, US government) to plug in a supercomputer and steal control.
This is either a bubble or probably the most awesome J-curve of the decade.
Either way, I am waiting to see what happens. I have more than enough bitcoin for a black swan hedge. I am also going to be with bitcoin to the bitter end or the ultimate victory over state-controlled monetary system.
"This is either a bubble or probably the most awesome J-curve of the decade."
The average American isn't smart enough to understand what bitcoin is, how it works, how to buy them, how to spend them, etc. In five years bitcoin is going to be just another failed standard like i-names or GPG, something that doesn't ever get used except for in very niche enterprise usecases or when nerds are trying to impress other nerds.
So say I'd have a blog with a huge reach. I hear about bitcoins. I buy a million for $4 each. I blog about it. Next day it's at $8. I'd sell the bitcoins, maybe 10000 a day to not let the market crash, and in 3.5 months I've got $4 million more than I used to.
And I thought bitcoin wasn't going to go anywhere, I made about 3000BTC back in 2009 and just over time forgot about it and lost my 'wallet' id (a hash), kicking myself in the ass now.
There's pretty decent volume and the bid/ask spread is gradually tightening. Just for some perspctive, the US Dollar index futures trade about 15,000 contracts a day, (granted they are much easier to convert).
Just as a quick reminder, since most people commenting don't understand how bitcoin generation works.
It is not possible to "corner the market" by having more gpu power than other people. The btc algorithm was designed to only produce bitcoins at a constant rate. Adding a million more systems trying to calculate the answer to the next hash block only makes it a million times slower.
If the bubble were to pop tomorrow and it went back to being a network with only a few hundred low power systems, the btc network will auto correct to produce new bitcoins in relation.
It's very easy to game the system. You need roughly 30% of the network's total computing power and you can "steal" bitcoins from others.
The creator of bitcoin outlines a strategy for stealing bitcoins in the FAQ. In it, he claims that 50% of the computing power is necessary to do this. Later improvements to the technique (and simulations by various people) have shown that you can do it in much less, possibly as low as 15% of the computing power.
Bitcoin is highly vulnerable to a nation state or intelligence agency that wants to own it. It is also highly vulnerable to rich entrepreneurs who want to make a profit by cornering the market.
The NSA could destroy bitcoin in the blink of an eye with only a tiny fraction of their supercomputer power. Likewise for botnet operators and other professional extortionists who no doubt have their eye on bitcoin. The fact that bitcoin hasn't been destroyed yet is just a demonstration that the currency is not really worth anything right now.

Which means you mine them as fast as everyone else used to, while everyone else mines them at one millionth the rate they used to.
There's this received wisdom among sociologists that three prerequisites for a stable country are laws, someone to enforce them and a judiciary. I mention this since Bitcoin is creating it's own economy which is analogous to a virtual country. The major benefit of Bitcoin, it's lack of jurisdiction, may also be a disadvantage. As the first disputes arise, hopefully a body of precedent will be developed that strengthens the currency rather than destroys it.
An economy is based more on the trust between the actors within it than on its medium of exchange or the goods and services being exchanged. Bitcoin doesn't address this aspect. Because fraud and collusion are still possible in a Bitcoin economy there exists the possibility of both currency instability and the creation and enforcement of monetary policy.
An irrational public can be just as damaging to a currency's value as an unwise central bank or government.
Regardless, I find Bitcoin to be a very interesting system and I'll keep tabs on its development.
It looks like had I know the article was going to air, I could have doubled my money almost overnight. I would expect the price to stop dropping any time now.
Oh goodie, another part of our economy that ignores the true cost of energy creation. Has anyone looked at models of how this system might work if the miners had to pay significantly more money for electricity?
With the term "energy creation" you are ignoring the first law of thermodynamics.
But apart from nitpicking I agree with your point. In the end the whole economy thing boils down to "having the capacity to actually do stuff.", which ultimately requires energy.
Giving a unit of currency to someone is like giving a promise that he can actually DO something later.
In the case of bitcoin, the energy is used (dissipated to heat) during the creation of the currency itself. No substantial backing of the curency beyond that.
But then again this is true for any other currency floating around right now.
I've been watching the price of BTC rise pretty steadily in the last few days but I can't bring myself to believe that this price range is in any way sustainable. $4 per bitcoin? Not even the EUR and GBP have ever reached that in my recollection. I guess it if does stay like this mining is going to become pretty lucrative and certainly financially worth it.
$4 per bitcoin? Not even the EUR and GBP have ever reached that in my recollection.
Keep in mind that the exchange rate is a function of several inputs, one of which is the rather arbitrary fact of how much total currency is in circulation. There are many fewer BTC than USD, EUR, GBP, etc. (about one million times fewer, to be precise). And conversely, there are many more JPY in circulation, which is part of the reason the yen is much cheaper than the US dollar.
That doesn't mean there's not a BTC bubble. There may very well be. But you can't do the comparison you just did and expect it to be meaningful. If the BTC protocol had specified the decimal point one place to the left, BTC would be trading at 0.40 USD right now, not 4.00 USD. There'd just be 10 times as many.
What you have to do is ask how much total wealth the world will want to store in BTC, and then divide that by how many BTC there are. The answer to the first question is a huge unknown. The answer to the latter is specified by the protocol: 21 million.
That's pretty much the same as saying: What? $3 for a Big Mac? (I'm assuming they're $3).
There will only ever be 21 million BTC. Considering that according to the US deficit, there exists at least 13 trillion USD, that would put the final exchange rate at $620K USD per BTC.
That is only possible, mind you, if BTC actually catches on.
How can the SEC not be all over this? It's amazing to me that it has either escaped its attention or -- possibly -- it has absolutely no idea what to do about it.
If bitcoin were an equity, then the U.S. Securities and Exchange Commission might be looking at it.
But even if they did ... if you are in Brazil, Russia, India, China, or wherever, ... how would what the SEC does be relevant? (yes, I'm being purposely obtuse, but remember that bitcoin is data, and as such it knows no borders.)
