Bitcoin Exchange Value Halves After Chinese Ban 475

An anonymous reader writes with news of the latest major fluctuation in the price people are willing to pay for Bitcoins. From the article: "China's ban on its financial institutions handling bitcoin causes world's largest exchange to cease trading, halving the value of the currency from $1,000 to less than $500 in a matter of days. The country's central bank took a hard line on Bitcoin in early December when it banned financial institutions from handling the decentralized crypto-currency, and as a result BTC China, the world's largest bitcoin exchange, has stopped accepting deposits from its users." Just watch that line trend downward.

      • Fixed rate home mortgages in the U.S. are backed by the federal government, who provides insurance in order to "incentivize" ownership. For reasons unrelated to the present discussion, I think this is a bad idea, but that doesn't influence the main point that mortgages in the U.S. tend to have lower interest rates than in most other countries.

          If you actually had to borrow that money from people who are investing to, y'know, save for their retirement or rainy days & such, interest rates would be higher. Instead, they have to watch while their savings dwindle in true value due to inflation (the aforementioned printing).

The mining reward halves every 210,000 blocks (about 4 years). It dropped from 50 in Jan 2009 to 25 in Nov 2012, the current rate. The next halving, in about 3 years, will reduce it to 12.5 bitcoin units per block.

      Both parties in a trade value what they are getting more than what they give.

      For a certain definition of value, yes, but not necessarily for the common one. In an idealized market, you do hope this is true for the common definition also: people have independently assessed how much they value some commodity, and offer a price accordingly. The price then converges on some aggregation of values.

      But in real markets, this is often recursive: someone is offering $x for a commodity not because they themselves consider it to have a certain value, but because they think they will be able to resell it for $(x+y), due to market fluctuations. They may themselves consider it a worthless pile of trash valued at $0; day-traders, unlike value investors, don't make trade decisions based on their own assessments of the underlying value of the commodities or equities they're buying and selling. Instead they base their decisions on statistical estimates of market dynamics, independent of whatever the underlying item is and whether it may or may not have any value at all (models often don't even consider the underlying item in the equation).

    Kind of a sideline approach here...

    This is the clearest evidence yet that the pro-bitcoin libertarian segment misunderstand how government control works. The argument goes "government prints the money, and tracks the money therefor can tax me." The presumption of bitcoins is if the currency doesn't come from the government, they don't have any means to control it.

    Good ol' actually tyrannical China comes along, and does the thing any government is capable of doing. Saying "if we catch you dodging our system, our system will throw your stupid self in jail." Poof.

      I think only the most naive anarchists argued that (and I've called them on it many times before in various Bitcoin forums). The gamble being made there is effectively that given a choice, a government would choose not to become totalitarian and oppressive, and would prefer to give up some control over the financial system.

      Well, only an idiot would believe China would do that. They are already totalitarian and oppressive, no surprise they'd be willing to jail anyone who uses Bitcoin.

      In contrast, many European countries are sorting out how they're going to handle it. See the recent announcement from Denmark saying that Bitcoin is fully legal, and people who want to run exchanges don't even have to be regulated as financial institutions at all! It seems very unlikely that the governments of Norway or Denmark are going to start jailing anyone who sells sandwiches for coins.

      America is somewhere in the middle. It's not as free or liberal as most of the smaller European states, but it's not as oppressive as China. Hence the confused approach there where the US government is saying one day Bitcoin is cool and it's all OK, and then next day threatening Bitcoin businesses with jail time. They can't quite decide which direction to go in, it seems.

      • And, that seems like a perfectly reasonable belief. But bitcoin suffers from an excess of "true believers".

        Huh? There's no confusion at all. The US Government is 'totally cool' with Bitcoins so long as you comply with existing financial regulations. The Bitcoin business (the physical coin dealer) wasn't threatened with jail because he dealt in Bitcoins - but because he didn't so

    • It is china, where they execute people for bankrupting a company. I doubt they'd just throw them in jail because of that.

      • Part of having inappropriate punishments for crimes is that they aren't necessarily going to correspond to any metric in particular, but the whim of the leadership. That includes light sentences sometimes.

        • Oh I know, I'm just expecting a news report that china executes someone for BTC use within the next year or so. After all, it is china.

          • Remember that the overarching goal of government in China is "glorious harmony." They want a monoculture, and they're more inclined to use work-camps with no trial involved than bring people up on summary charges and execute them. You basically have to be an image problem to get executed in China(they kill fewer people than the U.S., for example).

            • And that means a very vocal and visible dissident, or a high profile business refusing to comply. It's not like china hasn't had many of those cases.

    I wish people would stop calling these "crypto-currencies", because it is a total misrepresentation of what these things are. They are crypto-commodities. BTC is just like gold right now - it is not used to transact, it is used as a value store - except it is much worse as a value store because it is orders of magnitude more volatile. No one can use BTC as a currency because its value fluxuates so wildly. Everyone who is SUPPOSEDLY using it as a currency just has it pegged to the US dollar with a live update.

      The inability to charge back is the #1 reason that prevents any consumer from perceiving it as a safe currency against vendor fraud. It serves no benefit to the consumer.

      Minor correction - dispute mediated transactions have been a part of the design since day one [bitcoin.it]. The problem is lack of surrounding infrastructure like "file dispute" buttons in wallets and the various protocols needed to organise that, companies that run dispute mediation services with those protocols and so on. But there is widespread consensus that it's a good idea and basically, it's just waiting for someone to do the design and implementation work to make it happen.

      Its incredible volatility is the #1 reason that prevents any vendor from seriously adopting it.

      It's certainly a PITA at the moment, yes, although when Bitcoin is out of the public eye and governments aren't busy banning it there have been relatively long stretches of peace and stability. During those times you HAVE seen vendors price things in Bitcoins, actually, although yes most prefer to peg to an exchange rate.

      Over time the instability will go away because governments will all decide on their policies around it, the technology will mature and become boring, most people will have heard about it and decided what they think, etc. The huge volatility you see at the moment is because almost every day there's some important piece of news that affects people's perception of future value.

      As to the /r/bitcoin posters, yes, the over-excitability there is quite something. But that doesn't mean all people who use Bitcoin or like it think the same way.

    When a couple of my friends started posting "now is a great time to buy into BitCoin" messages on my Facebook feed a couple of weeks ago, I had a feeling the BTC price was about to take a strong downward turn. It is never a good sign when the "true believers" begin actively recruiting new buyers into a price bubble.

    The collapse of BitCoin as a speculative investment is inevitable, and its own success will be its downfall. The speculative frenzy over BTC is based strictly on artificial scarcity. The problem is that there are an infinite possible number of cryptographically signed digital currencies. If only X amount of gold exists in the world, there is no replacement for it, assuming you desire the exact physical qualities of gold. But if only Y digital coins exist, it is trivial to create another digital coinage with a slightly different protocol that behaves exactly the same way as far as a user is concerned.

    The boom in BTC has led to several new competitors, with similar frenzies growing around some of them. And given the low barrier to entry, you can expect more and more competing digital currencies to appear. It is only a matter of time before people realize that they're fighting over a particular set of tulip bulbs while standing in an infinitely large field of tulips. Once that happens, the speculative bubble will pop for good for all digital currencies. In the long run, this is a good thing, because once the speculators are gone, some digital currencies may actually prove useful as a real medium of exchange, with values that don't fluctuate wildly from one day to the next.

    Bitcoin has a legitimate purpose; a truly portable store of value not needing physical storage that is also not under the control of any government entity has a fundamental value. The true mark of the legitimacy of any currency is the existence of as-of-yet unknown 3rd parties willing to accept said currency. Shells, salt & grain have all been used in the past because a person accepting said currency trusted that somebody else would take that same currency in return for goods or services at some future date. Bitcoin is going to swing between overvalued and undervalued for a while, but eventually a critical mass of parties willing to trade in Bitcoin alone will exist. Someday a farmer will accept Bitcoin for his wheat, and then use those Bitcoins to pay for his diesel and tractors and not once will any party have to convert Bitcoins to <insert fiat currency here.>

    It make take a while, but so long as Bitcoin remains uncorrupted by counterfeiting it will stabilize because it will remain out of the sphere of government influence.
