Bitcoin Plunges After Mt. Gox Exchange Halts Trades

krakman writes with this excerpt from Bloomberg News: "Bitcoin plunged more than 8 percent [Friday] after a Tokyo-based exchange halted withdrawals of the digital currency, citing technical malfunction. Mt. Gox, claimed in a blog post it needed to 'temporarily pause on all withdrawal requests to obtain a clear technical view of the currency processes.' It promised an 'update' — not a reopening — on Monday, Feb. 10, Japan time. This is day after Russia's Prosecutor General concluded Bitcoin and other digital currencies are illegal under current law."

      I believe it is called a "stress test", one of the techniques that banks use to test the resilience of a trading system and how much liquidity it has. If they suddenly shutdown the exchange of currency, the punters are forced to make trades using other resources. How much of that other currency is used gives an idea of how is available. The Russians and EU did the same by restricting physical money currency transfers. The EU figured out there was black market the size of the GDP of the entire region.

    I don't understand how bitcoins or gold either one retain their values.

    Bitcoin is a bubble, though as with every other bubble there are delusional people who assert the emperor is not naked/that it all somehow makes sense. It doesn't... the valuation is absurd.

    As for gold, I think the explanation is a mixture of inertia, rarity, resistance to governmental manipulation, and lack of corrosion.

    Being able to beat it into a thin leaf is not a real explanation ("ZOMG! You can hammer this *how* thin?! SHUT UP AND TAKE MY MONEY!" said essentially no one ever). Saying it is valuable for jewelry begs the question (i.e. it's valuable for jewelry because its rare and expensive, but it's supposedly rare and expensive because it's valuable for jewelry?)

    So, it really comes down to "it's always been this way", but everyone can be reasonably certain that there won't be a sudden massive increase in supply, and that their holdings of gold won't corrode away into nothing. Furthermore, the government cannot simply pass a law saying that there is now twice as much gold as there was yesterday; this security against manipulation is certainly a valuable feature (well, unless you believe Krugman, who thinks that the government should always be able to manipulate currencies).

    Virtually anything you might buy or sell derives at least some of its value from faith, and currencies are no exception to this. In other words, as long as a sufficient number of people believe that 1BTC is worth ~$680, then 1BTC is indeed worth ~$680.

    This is even true of gold to a certain extent - its value goes up and down too, though it's seldom as volatile because it has other uses beyond currency.

    When something happens to shake that faith, the value drops. When something happens to strengthen that faith, the value rises.

    Any currency that isn't backed by something tangible (eg. a precious metal) by definition derives more-or-less all its value from faith. This isn't usually a big deal - most countries came off the gold standard decades ago - but one side-effect is that if your country's government is unstable, there's a very good chance your currency will follow suit in short order. For extreme examples, see Zimbabwean dollars, Afghan Afghanis and German Papiermarks.

      It is self balancing over:

      It is possible that large processing node, like 65nm ASICs will stay marginally profitable even then for some time - when compared to electricity and human resources costs.
