What's a good way to short bitcoin?

There are derivative markets where you could purchase an option to sell bitcoin at a set price in the future. If the price falls below your target by then, buy up cheaper Bitcoins and sell them at profit.

take some forwards @ mpex.co

There are a few replies here that seem to be reacting negatively to the OP due to the tone of the submission instead of the content. To be clear, deflation is categorically bad for a currency. It's terrible, like great depression terrible. The reason it's bad is that deflation makes it more profitable to do nothing than to invest. When this happens, people react by not spending money. The market dies. While inflation…

> deflation makes it more profitable to do nothing Isn't deflation for the buyer seen as inflation for the seller and vice versa? Why would you then not (applying your deflationary spiral model) expect a "market death" from sellers not selling under currency inflation?

Think of it this way:

Person A: one who gives Bitcoins in exchange for Widgets. Person B: one who gives Widgets in exchange for Bitcoins.

Notice the symmetry. The name buyer and seller are arbitrary designations depending on what you consider the currency and what you consider the good being sold.

The inflation/deflation symmetry exists but it is not in the same terms. Deflation for bitcoins is the same as inflation for widgets. The widget holders are desperate to trade their widgets for bitcoins since their widgets's purchasing power is decreasing, but bitcoin holders are reluctant to buy widgets since their value is decreasing.

1. Unjustified moral reference to "shameless hoarding". Where is the magical date when your property belongs to you for "too long" and you should give it to someone? And to whom exactly? 2. Why take credit for business if you can save your own earned money which appreciates over time and have 100% stake at your own project? 3. How deflationary spiral is supposed to happen? Will people be paralyzed and dead of hunger…

Property rights are a fiction invented and enforced by society. Therefore, it's not inappropriate for society to occasionally have opinions on how property should work. Some of the ways people handle their property is detrimental to society. If enough people do it, hoarding capital is one of them.

You did not answer my questions regarding hoarding. If you don't have an answer, how are you so sure about moral character of "hoarding"?

A currency can't make value out of nothing for long. Why, my dear fellow, that is exactly how every government-backed currency works today! And, thanks to its inflationary nature, it becomes virtually worthless over time: Although inflation has remained low in recent years, it ravages the value of paper money over time. A dollar in 1900 is only worth about $0.04 in today's currency. Quoted from: http://finance.yahoo.…

Ah yes, of course, but that currency is undergoing inflation. Bitcoin is rapidly deflating. Huge difference.

My point was simply that no currency is backed by "stuff" any more. I was responding to your criticism of Bitcoin ("A currency can't make value out of nothing for long").

Of course Bitcoin is deflating - it was designed that way. And of course fiat currencies are inflating - there is no limit to how much can be printed except reason, which is apparently in short supply.

If they trust you, it's a matter of seconds. And anyway, try to do that in 20 minutes with gold.

If they trust you , they can do it with gold too. "I owe you an ounce of gold."

They need to trust you for 10-20 minutes before confirmation, not forever like with borrowed piece of gold.

Some people here seem to think that this is temporary, that sometime in the future Bitcoin will stabilize into a glorious future global currency -- never mind the new class of cryptobarons it will have created from its inner circle, through shameless hoarding. My question is, what then will happen when Bitcoin stabilizes, that is, when the time to new coin mined approaches practically infinity? Let's assume the globa…

I have never understood the inflation is good argument. Looking at PCs, DVD players, etc. it seems price deflation has been great for the consumer and overall "market". Perhaps it has been bad for the manufacturers, but the overall society has benefited from the deflation of those goods.

Electronics become cheaper due to technological improvements, that is, positive supply shocks. That means our real wealth is increasing. That's a good thing!

Electronics might also became cheaper due to, say, someone setting money on fire, so there's less to go around. Clearly in this case our real wealth would not be increasing, so it's not good. But it's not obvious why it should be bad, either.

The reason it's bad is due to our psychology. If the money supply shrinks (and nothing else changes), prices and wages must both go down. But people hate the idea of negotiating a lower wage, so instead wage drops are accomplished through layoffs and unemployment. That's bad because it means that people aren't working: the economy's real output is reduced.

So inflation provides a buffer that allows the economy to adjust wages downwards in a way that we find more palatable than negotiated nominal wage decreases.

Why buy a smartphone when next year's smartphone will be better in every way?

Because today (and every day between now and next year) you can use that smartphone to do things that you can't do without a smartphone. So yes, the smartphone has lost money value, but you as a person and in your life, have gained. Not so with bitcoin.

Unless, you know, you actually want bitcoin. Maybe you want to buy something now with bitcoin (especially something that's more difficult to buy with government currency, like online gambling or illegal drugs), or maybe you just think bitcoin is cool.

> It's only purpose is to allow you to buy other stuff. There is certainly utility in being able to buy stuff that cannot easily be bought with traditional (government) currencies. Namely, things that are illegal in various countries, like drugs or gambling.

You're saying that drugs cannot easily be bought with government-issued cash? It's totally the other way around: drugs are easily and frequently bought using cash, and vanishingly rarely bought with bitcoins.

I would consider the Silk Road to be fairly large. Obviously, it's tiny relative to the entire USD drug market, but bitcoin is also tiny relative to USD. But the point is, you simply cannot deny that there is actual demand for bitcoins caused by the fact that the Silk Road only uses bitcoin.

Deflation is just one form of asset appreciation. If this line of reasoning were true then we would never see anyone selling anything that appreciates in value. But this is a very one-sided way to consider this scenario--it only takes into account the supply side. When the asset is appreciating, the demand side takes this into account as well and is willing to discount their asking price to take this into account. Yo…

One problem here is that you're considering the currency as an asset that should appreciate. The argument of most economists today is that currency should not appreciate because it encourages hoarding what is essentially a useless non-good, it's just a token for convenience of value transfer. If real goods appreciate, it's because the value offered by that good to the marketplace has increased, so the market pays a c…

You're just noting the difference between a centrally-managed currency and one that's not. The value of bitcoins tends to move quite a lot lately, so it's like trying to price something in AAPL stock or something right now--you have to peg the value to a slower-moving reference currency. (And that's typically how BTC-denominated goods are priced, for example on the Silk Road the product prices are pegged to the USD.)

But that's not to say that centrally-managed currencies don't fluctuate either, because they do--just, typically, in the other direction. If I tried to find a gas station that would sell me a gallon of gas for $2USD today I'd be out of luck, but 2-3 years ago I'd be able to go anywhere in America and get that deal.

That is a good point and that is a big weakness of bitcoin. Fact of the matter is this crazy appreciation is not very good for the currency. It encourages hoarding and discourages commerce. For all the stories about appreciation I do not hear many stories about bitcoin actually being used as a currency. And why would it be. Most people holding it believe it will go up in the future. Why would they spend their bitcoins on commerce if they think those bitcoins will be worth ten times their value in the future.

Currently bitcoin is not a currency but a very speculative investment.
