Ask Amir Taaki About Bitcoin 768
"Bitcoin," says the project's website, "is a peer-to-peer currency. Peer-to-peer means that no central authority issues new money or tracks transactions." Wikipedia offers a readable explanation of the underlying technology. In (very) short, Bitcoin uses a distributed database and public key encryption to allow users to reassign ownership of units of Bitcoin currency (BTC), and does so in a way that can keep the user's identity private. Bitcoin isn't yet accepted the way credit cards are, but it's more than theoretical. You can buy (some) things with Bitcoin, and trade the currency itself.
Now, you can ask question about Bitcoin of Amir Taaki, a developer of client interfaces and stock trading software for Bitcoin, and owner and operator of trading exchange Britcoin.co.uk. Amir requests that questions focus not "so much on the mining (too many people get focused on that
when it's a minor aspect of Bitcoin) nor simple technical questions (people can
go find that info themselves on Wikipedia/the forums/sourcecode)," but rather on the harder-to-answer questions. Reading some of the related stories listed below may give you ideas on what those are. Standard Slashdot Interview rules apply: ask as many questions as you want, but please keep them to one per comment. Amir will get back with his answers.

This all works wonderfully for the people who have the financial understanding of markets and such schemes. Geeks generally do not. All they see is this program that they can use to make money with their hardware. They forget that all the traditional pump and dump schemes and others still apply. Actually not only do they apply, they're safe to pull of with Bitcoin because it's legal, the market is really vulnerable to it and most people using it do not understand what is happening. Those who trade stocks or forex generally have even some understanding of how the market works. Bitcoin users generally do not, as they're just normal users.

That doesn't mean bitcoin doesn't have it's uses.

Gold has no inherent value either. Gold only has value because it is hard to come by which makes it a great object to use for currency as it's hard to "duplicate".
BitCoin is the same. A currency is only as useful as it's ability to not be duplicated. It's much harder to create a bit coin than it is for the government to print off more money and deflate the USD.
The problem that occurred is someone artificially increased the exchange rate of bitcoin by creating artificial demand. A newly create currency is going to be volatile for a while before it stabilizes.
As bitcoin gains more monetary value, a single person's influence will drop. After a while, a single person won't be able to make a noticeable difference.

The value of gold on the free market is also far above the intrinsic value - if fewer people saw gold *purely as a medium of wealth storage* then the value would plummet. Gold is in fact very like a fiat currency, right down to the production and distribution being controlled and manipulated by just a few big players, so its not as if the supply of it is constant or finite. It's not quite as vulnerable as a fiat currency to devaluation, but it is still only as valuable as people think it is.
Bitcoin is an interesting idea, in that it tries to provide a finite supply of coins (once the initial period of production is over) which will mean it cannot be devalued by issuing more - that would make it an ideal currency for a government and/or a public which valued fiscal responsibility. Unfortunately no-one does.

If you have gold, or any other commodity, then there are people willing to pay you for it. This is not the case with BitCoin. The cryptographic hashes have no value because there's nothing that you can do with them. It would be possible to create a currency backed by the promise of future computational work, where you could gain currency units by doing useful work (e.g. protein folding, running MapReduce operations for Google, and so on), but that's not what BitCoin does.
Even fiat currencies like the US dollar have more value. They are not backed by a commodity, but they are backed by the promise that the US government will accept them in payment for all debts, including taxes, which means that they can be traded for commodities easily. There is no such guarantee with BitCoin.

But is gold worth more than it would be otherwise, because of its historical use as a currency?
Gold is a commodity. Just like any other commodity, it is susceptible to fluctuations in the market that move it away from the price that would be optimal in a simple supply and demand economic model.
This is demonstrably false. There are people willing to pay real dollars for Bitcoins.
Sorry, to clarify I mean that there are only speculators in the market, there are no consumers. In a commodity market, you have three kinds of actors: producers, consumers, and speculators. Producers create the commodity. In the case of gold, they dig it out of the ground, or possibly recycle it (I used to know a scrap dealer who bought old computers to get gold out of the circuit boards, for example). These people insert the commodity into the market.
Consumers take the commodity out of the market. In the case of gold, they are people who have a use for the metal, such as jewellers or board makers. In the case of wheat, they are typically people who make flour (itself a commodity, for which these same people are a supplier).
Speculators are somewhere in the middle. They buy and sell without consuming. Their goal is to make money from the noise. They are allowed in the market because a small number of them can insulate producers and consumers from spikes in supply or demand.
Without speculators, someone growing wheat (which takes a significant fraction of a year to produce) would not know how much they could sell it for when it was grown. They'd be taking a significant risk: if the demand for wheat dropped significantly, then there would be problems. To insure against this, they offer wheat futures at a price that they consider fair. These are a promise to sell wheat at a fixed price in (for example) a year's time. Similarly, someone with a need of wheat in a year might buy a wheat future, insulating them against changes in the price in the opposite direction. Speculators are allowed in the market as buffers. Their presence means that there will always be someone willing to buy or sell wheat futures, and people looking at planting wheat now can look at the market price to decide whether it's worthwhile.
If there are too many speculators, then the price stops being set by the price that speculators expect to be able to sell the commodity to consumers for, and starts being set by the price that they expect to be able to sell it to other speculators. This causes wildly unstable markets (see the wheat market since about 2007, when the US removed the constraints on the number of speculators allowed in the market, for example).
In the case of BitCoin, the market contains an increasingly small number of producers, no consumers, and a lot of speculators. My comment was meant to say that there were no consumers in the market, and I thought this would be understood without the need for Market Economics 101.

This renders it quite useless as a viable currency. (The current value of all currency in circulation is currently far too small to be viable, and the deflation required to get the BitCoin economy to a size where it would be a viable currency is far too high, leading to hoarding that would exacerbate the problem.) At the very least, it should have at least leveled out to a linear slope to account for increase in gross economic output.

Yes, I realize PayPal is unreliable, and you should never keep your money there for any length of time. But what does that have to do BitCoin's usefulness; the analogy is simply is not valid.

What about the lack of inflation?
It's long known that economic growth is severely stunted without some measure of inflation. Adopting bitcoins for the global economy would mean that policymakers lose control on money supply, and while there are advantages in this, disadvantages far outweigh them. Additionally, adopting a global currency standard will deny governments ability to influence currency rates robbing them of yet another way to control the economy.
Is there any plan to solve this? Maybe a system of independent bitcoin 'roots' operated by governments would help?
It's even worse than a lack of inflation (Score:4, Insightful)
The BitCoin system has guaranteed deflation because lost hashes disppear from the monetary system forever. (Lost, destroyed or hoarded US currency can be replaced by the Federal reserve with a few keystrokes.) In addition, the current total value of the BitCoin currency (expessed in any normal monetary unit you'd care to name) is far too small to be a viable currency. It would have to deflate by several thousand percent to be any more than a niche currency. Since no one would volunteer to be the victims of such deflation, BitC's are doomed to irrelevancy.
I hope they didn't plan on deflation (Score:3)
Planning on deflation to me says that they were building a pump-n-dump scheme, and knew it. I am hoping that instead it was a result of a hopeless understanding of economics, and absolutely no clue about what strict limits on monetary supply does to trade growth and the viability of a currency.
You can tell they made an attempt at "solving" the deflation issue by making it minutely subdividable, which effectively solves the liquidity problem. (Though it does all kinds of wonderful things to the system's sc

So far, in the bitcoin community, you see miners, speculators and marketplaces. The system is well designed to attract greedy people, but not to perform useful transaction.
In money history, metal coins are successful for trade when there metal value is weak. If they contains too much gold or silver, people tend to keep them. It's the same for bitcoin: the built-in deflation encourage actors to accumulate bitcoins, not trade them.

What is the advantage to users? (Score:3)
Why would any individual gain any advantage by participating in bitcoin, except that some early adopters may have been able to realize profits at the expense of later adopters? The closest the bitcoin FAQ [bitcoin.it] seems to come to answering this is:
Is Bitcoin a Ponzi scheme? [...] Bitcoin has possible win-win outcomes. Early adopters profit from the rise in value. Late adopters profit from the usefulness of a stable and widely accepted p2p currency.
The final sentence is what is supposed to make it not a Ponzi scheme. Let's break that down into pieces:
Stable: I live in the US, so this doesn't do much for me. The dollar has had a relatively low inflation rate for decades now, whereas bitcoin could become completely worthless at any time. Even if I was living in a country like Venezuela, which has crazy inflation, I would be foolish to hold any significant portion of my assets as bitcoins. I'd be much better off stuffing US currency in my mattress. If I was the type of libertarian who gets upset about "fiat currency," I could put my money in real estate or gold coins.
Widely accepted: It's not widely accepted, and I don't think it's plausible that it ever will be.
