This is a fantastic article, and it highlights some of my worries as a Bitcoin lover. It would seem the only times one would use Bitcoin over USD is if a Bitcoin-specific benefit (for instance, anonymity when buying illegal goods) outweighs the cost of using BTC over USD. In a deflationary economy I can't fathom why someone would spend BTC over USD buying a legal good, except maybe for the kick of having spent Bitcoin.
2% less fee, than credit card. It's enough to take over the payment world. And it's only one of the advantages.
The 0.0001 BTC Transaction fee tacked on to every BTC exchange is only going to get worse and worse as BTCs's exchange rate goes up btw.

What used to be a rounding-error that happened on every BTC transaction is now a $0.10 tax on every BTC transaction. If BTC continues to deflate, the transaction fees on BTC are going to become quite sizable.

This is a known issue. The current design around smart fees is described here: https://gist.github.com/gavinandresen/6548612

The high level idea is to introduce market mechanics to bitcoin fees, with the expectation that competition will drive prices down.

If the deflation ever becomes stable(ish), the increase of value can be accounted for in the price, as sellers will have a reason to prefer BTC and offer discounts (not to mention eliminating all those 2.9% credit card fees). We already buy all sorts of optional goods, even if those goods will depreciate compared to letting money sit in a bank account and accrue interest.
Bingo, we have a winner.

What is important is NOT deflation vs inflation, but to keep that value _stable_. USD inflates at a rate of 3% year over year, so we can compare investment vehicles against the rate of inflation and see whether or not they are good deals.

But since BTC is extremely volatile, its impossible to use it as a unit of value. Until it settles down and becomes predictable, it will become impossible to form a "BTC Economy".

I think of it as owning shares of stock in a DAC (Distributed Autonomous Corporation). At some point, those shares of stock might become worthwhile as a day-to-day currency.

As is, though, I think it's already more stable than local currencies for some parts of the world (though perhaps still not more so than the dollar).

It isn't a stock however, and never will be. The reason why people invest in companies is to make more money. Companies may not offer dividends today, but eventually they will. (IE: Even Apple, once allergic to the idea of dividends, offers a regular one to its investors). Any company that churns a profit will eventually share those profits with its investors.

"Owning" BTCs is not about churning profits eventually, its 100% about speculating about its future value. Building BTC Mining equipment is where the real "value" of owning BTCs is in, since that puts you in control over a number of BTC transactions.

The BTCs themselves can NOT be compared to stocks. Stocks mean you actually own the company, you eventually partake in that company's profits... and even partake in choosing the board of directors. (who then in turn... choose the CEO).

A BTC on the other hand, is like speculating on Oil, Gold, or Timber. Its a commodity, not a "share".

I suppose the proof-of-stake coins act a little like stock, in that one gets to contribute to the 51% that writes the rules of the network, but I take your point.

Ultimately, crypto-coins are a new type of financial instrument that don't fit cleanly into either currency or commodity (given that they're not exchangeable for something tangible). Owning BTC is subjectively stock-like, in the sense that its present value is based primarily on network effects, and its future value is highly uncertain.

A few thoughts:

1) Conversely, why would I want to keep my wealth denominated in a currency that loses 2% value every year?

2) Supposing 90% annual deflation forever, as this article does, is disingenuous. Bitcoin is currently a 5 year old technology, and of course it will have periods of significant volatility. In the long run, bitcoin will stabilize, and deflation will be on the rate of global economic growth, currently estimated at around 2% [1]

3) In the long run, people could keep their wealth denominated in bitcoin, and spend dollars. There you have the best of both worlds: your wealth storage is deflationary, and your spending currency is inflationary.

edit: 4) Perhaps most significantly, remember that bitcoins and dollars are exchangeable at any point in time. Any dollar you spend on goods/services is a dollar you could have spent on bitcoin. Have bitcoin enthusiasts completely stopped spending dollars on goods/services?

[1] http://www.wolframalpha.com/input/?i=global+gdp+growth

Because losing 2% to 3% every year is actually quite stable. Its so stable that the typical person doesn't notice it.

Deflation at the rate of 100% over two weeks on the other hand (ie: BTC's current rate of change), is absolutely and utterly ridiculous.

> In the long run, bitcoin will stabilize,

Why would this be true? Gold and silver have been around a long time, but both are still relatively volatile.

I mean, I hope you're right, I'm just curious where you think volatility ends up and why you think so.

The volatility of Gold and Silver is approximately 20% / year. There was a MASSIVE Gold sell off earlier this year, which caused a temporary spike of Gold Volatility to 60%.

In comparison, the volatility of BTC is approximately 6000% / year.

The magnitude of volatility is straight up ridiculous. The behavior of BTC is more like a penny-stock than any commodity on the market

> Gold and silver have been around a long time, but both are still relatively volatile.

Are gold and silver not less volatile than government-issued currencies, the long-term value of which has traditionally ended at $0?

> Are gold and silver not less volatile than government-issued currencies

Which government issued currencies? Government issued currencies are not all alike.

> the long-term value of which has traditionally ended at $0?

Fiat currencies only end if the issuing entity ceases to exist or abandons them, and even so the market value of currency issued may not become zero, so the claim about ending value is suspect.

More importantly, though, volatility isn't even related to ending value, so this claim would be a complete non-sequitur even if it was true.

>> the long-term value of which has traditionally ended at $0

> More importantly, though, volatility isn't even related to ending value

Yeah, come heat death of the universe, ending value of all currencies will look pretty similar.

> Fiat currencies only end if the issuing entity ceases to exist or abandons them

I'm curious - can you point to one example of this happening?

To my knowledge they've all gone to zero in a hyperinflation but I'd love to know of a counterexample.

> > Fiat currencies only end if the issuing entity ceases to exist or abandons them

> I'm curious - can you point to one example of this happening?

Obvious, clear, and fairly recent examples include all of the European currencies that were retired in favor of the Euro.

> To my knowledge they've all gone to zero in a hyperinflation but I'd love to know of a counterexample.

A number have been abandoned (and often replaced by a new currency with the same name) by the issuing state in the face of inflation (often not even at the level typically labelled "hyperinflation"), but the nature of the "fiat" in "fiat currency" essentially assures some minimal residual value as log as the issuing state remains functional as a state and does not abandon the currency.

E.g., the pre-1993 Mexican Peso was withdrawn and replaced by the New Peso after a long period of double-digit annual inflation, but it neither "went to zero" (prior to being withdrawn) nor suffered hyperinflation (monthly inflation >50%.)

Bitcoin volatility is the result of thin order books. Look at http://bitcoinity.org/markets/bitstamp/USD: you can move the market by 10%+ with "just" a few million dollars. You can't move the market for Euros or Yen with that much money.

In a bitcoin success scenario, this will change once bitcoin is no longer the sole domain of currency speculators, but starts seeing actual commerce. Some places where this could start:

1) International remittance. Wire transfers are slow and expensive. Bitcoin could make moving money internationall much easier. See, for example, YC-backed "Buttercoin": http://techcrunch.com/2013/08/20/buttercoin/

2) Merchant adoption. Credit card fees for online commerce are in the 2-3% + $.35 range. Bitpay currently offers 0% fees, instead charging a flat $30/month: https://bitpay.com/pricing

3) Micropayments: The "+ $.35" part of credit card fees precludes micropayments. Bitcoin could be used for things like pay-per-minute streaming.

Once these types of things start adding volume and depth to the exchanges, it will be harder to move the market, and that will add stability. Obviously, this will take a few years.

Volatile by what measurement? Hopefully you don't mean volatile with regard to the exchange rate with fiat currencies. Because that says more about the currencies than it does about gold and silver.
Currencies are stable (and losing 2% value per year) because governments actively manage the supply of money to keep it stable in the face of very volatile demand (caused by what Keynes called "animal spirits". Since demand will fluctuate Bitcoin will fluctuate wildly for the foreseeable future like the value of gold has done and is doing. Bitcoin will never be a stable, safe place to store wealth for that reason. It might be useful as a payment system where you quicly buy Bitcoin and give it to somebody for a product (who then quickly sells it again), but it will be to volatile for much else except speculation..
The government could keep currency stable by simply not permitting more to be created. Done. That's not the intention. The intention is to make sure the banks can loan out as much as they want when they want and then get bailed out when crashes occur.
Not true. If the amount of money in circulation was fixed, the fluctuating demand for it would cause its value (i.e. what goods/services it will purchase) will fluctuate with it.
It does that anyway. The currency itself would be stable and there would be no guessing games about what was going on with monetary policy since there would be no policy to discuss.
> The government could keep currency stable by simply not permitting more to be created.

That would keep one measure of money supply stable. It wouldn't keep the value of the dollar stable, though.

  ...fluctuate wildly for the foreseeable future like the
  value of gold has done and is doing.
The value of gold as measured how? Do you mean the price of gold in USD? Isn't that more indicative of the price of USD, and/or the price of cash vs. commodities?
No, since gold has varied far more in value than any inflationary/deflationary measure of USD.
How are you measuring gold's value?
Inflation adjusted dollars.
Inflation isn't the only thing that affects the value of USD. UDS's perceived value fluctuates with regard to investors' value perceptions of other currencies, commodities, etc.

Edit: If you think that USD has a fixed value, you are mistaken. You may use it as your reference point, but that just makes you blind to the fact that the perceived values of all currencies and assets are fluctuating all the time. There are some which are more closely tied together, and some which are less.

I still stand by the statment that gold is more volatile than the USD.

[edit] I have not done the analysis, but would wager that gold measured against a basket of goods or currencies is more volatile than USD similarly measured.

Why would deflation converge to the rate of global economic growth? I'd think that the opposite tends to be true, eg. the inflation is often correlated with growth.
Suppose the only good in the world is apples, and the only currency is bitcoins. There are 21 million bitcoins in existence.

In 2013, we produce 21 million apples, so we could say that each bitcoin is worth 1 apple. In 2014, we produce 42 million apples, which is 100% annual GDP growth. Each bitcoin is worth 2 apples, which is a 100% appreciation in the value of the currency, aka. deflation.

Just to explain why growth => inflation, frequently:

Grow the (effective) money supply with lending and deposit accounts, and apples / dollar falls. When things are growing, people know there is money to be made, and so expect they are more likely to be paid back, and so lend more freely.

Thanks. That was counter-intuitive for me, now I get it.
There's no such thing as free money. It's gotta come from somewhere, and it has to impose a cost somewhere.

Inflation in other currencies has a moderate, and mostly beneficial, cost. It encourages people to invest their money instead of just saving it, which leads to enhanced economic activity. Deflation in bitcoin only has value to the people "saving" their bitcoins, which sets up perverse incentives in regards to use of the currency as a medium of exchange.

Author here. First, regarding point 2, I use a period of time in which 90% deflation occurred (from the perspective of bitcoin-holders) and consider what affect that would have on profits in a bitcoin-only economy. I do not assume 90% annual deflation forever, though I do suggest that deflation will continue. If anything I wrote seems to suggest deflation will continue at a rate 90% forever, please point out where and I will correct it.
The article uses 90% as the sample figure. There is no direct statement that this is the type of deflation that will occur, but it seems unlikely that bitcoin prices will increase 10x every year, which is what it would take to have that level of deflation in the long run.

Using a lower number, like 5%, would have been more reasonable, IMO.

I the the second paragraph, I link to a chart showing the percentage increase of the price of bitcoin in USD between July 25 and November 25, 2013. That increase would correspond to roughly a 90% decrease in bitcoin price levels. People holding bitcoin would perceive this as 90% deflation, while people not holding bitcoin would perceive this as a relative appreciation of bitcoin to the dollar.

It is a completely reasonable number because it actually happened, and I point all of this out in the blog post.

The thing is the use of such a high figure means that it is actually the lack of stability that is at issue and not the deflation. Imagine we had a currency that was inflationary at a rate of 90%. Then there would be absolutely no reason for anyone to accept payment in such a currency. I t would be impossible to order materials to create widgets. Widgets would also not get made unless we had a more stable currency (or system of exchange) alongside our inflationary one.

It is easy to argue that it would be the rate of movement and not the direction that causes problems in transactions.

1) Conversely, why would I want to keep my wealth denominated in a currency that loses 2% value every year?

Because you have no choice. Currencies are imposed by a ruling power (in our case the government) by force. When you choose your currency is usually in form of asset. But you can not pay your taxes in gold. Consequently you can not live in the USA without USD and in Europe without EUR.

2) Supposing 90% annual deflation forever, as this article does, is disingenuous. Bitcoin is currently a 5 year old technology, and of course it will have periods of significant volatility. In the long run, bitcoin will stabilize, and deflation will be on the rate of global economic growth, currently estimated at around 2%

That’s speculation, might be correct. No one knows.

3) In the long run, people could keep their wealth denominated in bitcoin, and spend dollars. There you have the best of both worlds: your wealth storage is deflationary, and your spending currency is inflationary.

As that’s exactly how it should be. Currencies are inflationary to induce consumer spending more today.

edit: 4) Perhaps most significantly, remember that bitcoins and dollars are exchangeable at any point in time. Any dollar you spend on goods/services is a dollar you could have spent on bitcoin. Have bitcoin enthusiasts completely stopped spending dollars on goods/services?

Did they ever do that? Bitcoin enthusiasts never used bitcoin for buying services. BTC buys you anonymity where is required that’s a revolutionary quality for a currency to have. But other than that, bitcoin has nothing to offer compared to fiat currency for daily transactions. Changing money from BTC to USD (and vice-versa) is not enough straight forward, as of today, to allow the majority of the population to use it. If I give you 10 BTC today, you need days to turn them to USD, while if I give you EUR, you needs hours probably maybe minutes.

The 'depreciating currency is a problem' argument is true for the existence of any asset having a higher yield than your widget factory. Why wouldn't you invest in that high yield asset instead of your widget factory? In this way, you can view _any_ appreciating asset as a reference unit of account. It is just as easy to see your egg and milk purchases as units of the high yield asset and delay your purchases for the same reason outlined in the article. So, it's a nonsense argument.

If you have a strong prior that stocks are going to be worth 100% more tomorrow than they are today, why would you buy milk and eggs with your spacebux today? You could invest your spacebux in stocks, sell them tomorrow, and buy milk and eggs tomorrow! Therefore, no one will buy milk and eggs today if stocks are expected to rise in price.

I'm not sure whether this winds up being meaningful, but a difference is that more hops means more transaction costs.
The critical difference is that Bitcoin is intended to be a currency and not an asset. People use assets to store (and hopefully appreciate) value over time. People use currencies to conduct business and as mediums of exchange.

If you think of or use Bitcoin as an asset, you immediately nullify any comparisons with currencies because the two serve different purposes. You could, in principle, buy a house with, say, 10 cars. But that is not done in practice because the market for asset-to-asset transactions (bartering) is small and illiquid.

If you are willing to ignore Bitcoin's purpose as a currency and only use it as an asset, you need to consider what will drive its value in the long term. For most things, that value is just a function of the supply and the demand. While the supply of Bitcoins is fixed and the demand for items that can be bought in BTC is increasing, what will happen when everyone realizes that BTC is a better asset than currency and stops using it for transactions? It will become illiquid, and illiquid assets only have their tangible value. Since Bitcoin isn't tangible like a house or a car, its tangible value is zero.

For the record, I think Bitcoin has potential, but not with the present economic dynamics.

How you "think of or use" things has no meaning. Everything that is traded, whether "currency" or "asset" has a value that changes over time. Or do you not know that people invest in currencies?
I heard Krebs in a radio interview say that many criminals who are practical experts in the actual use of experimental currencies require something like Liberty Dollars for price stability.

Could a cryptocurrency build price stability in as a feature?

I know this is anathema to one of Bitcoin's founding principles, but what if the payout for each round of mining was adjusted based on the average transaction size in the last few blocks? If transaction sizes are going up, you're getting deflation, so the algorithm would increase the rate at which money is being printed.

Not sure how to control for the opposite, for inflation. Maybe some small percentage of the transaction fees each round would get destroyed by the system, instead of paid out to the miners (it'd have to be a small percentage so you could keep people mining). Maybe better just leaving anti-inflation out of the design, since it isn't yet a demonstrable problem, might not ever be.

You could fiddle with how aggressively the system fights for price stability, trading off against the reliability of profitable mining.

Don't we the customers and the capitalists already have the same situation with dollars? I could either buy a PS4 or I could buy some penny stocks. I could either try my luck with a startup or I could put that seed money into a CD or a fairly low risk index fund.

So it all depends on the actual realistic rate of deflation if Bitcoin ever reaches widespread use.

Except that Bitcoin's intended purpose is as a currency, so to make meaningful comparisons you would need to look at other currencies or currency substitutes (gold/silver/jewelry/etc).

Assuming that it reaches widespread use ignores the chicken and egg problem that producers of goods will not want to use it if the depreciation is too high. Currently you can spend bitcoins mainly through intermediaries and various online purchases that quickly convert the BTC to some fiat currency. I.e. pay a company for server space, they quickly turn it into dollars or euros to pay their electricity and employees.

But to be a legitimate, full fledged currency it will need to both be a reliable store of value (low volatility) and be useful for producers (minimal depreciation). It has neither right now, and I personally don't see a path from the present state to that ideal equilibrium.

"There is a limited supply of bitcoins". Not really true. Bitcoin is infinitely divisible (unlike a dollar). Having only 21 million is not an issue, because pretty soon we will be talking about micro bitcoins as the base unit of transactions.

And then there will be another Bitcoin competitor (Litecoin). And another. And another. We will never run out of bitcoin and equivalent products.

Stabilizing the price is definitely an issue. Can it be stabilized?

> why buy something today if it will be cheaper tomorrow?

Because you want it today.

The "fear of deflation" argument is now pervasive among monetary theorists. The argument goes that if people know that prices will fall, they will indefinitely delay all economic activity.

This ignores the time preference aspect of economic decision making. For example, I will buy my cup of coffee today rather than wait a day or week to save 1% because I WANT IT TODAY.

We've seen periods of significant economic growth coupled with falling prices.

Before going fiat, we had slowly falling prices in our nation's period of largest economic growth, the late 1800's.

(comment deleted)
Your analogy is flawed and completely unrealistic. BitCoin's fluctuations are insane, we're talking about ~ 15 times compared to last year. Would you seriously use a bitcoin to buy a cup of coffee today ?
Right, "Price Stability" is a different thing with real merits.
I don't use Bitcoin at all.

I'm just talking about the general idea of inflation.

I'm not arguing the merits of Bitcoin.

What's your opinion on inflation as an economic driver? I'm also a fan of deflation (as I want to save my money) but the Federal Reserve and other central banks (Japan being a notable example) are advocating for higher inflation, which begs another question:

Are they right and both deflation and inflation can supply economic growth? If so, does that mean another factor is the main proponent for growth?

> What's your opinion on inflation as an economic driver?

My opinion is that inflation does not drive economic growth.

> Are they right and both deflation and inflation can supply economic growth?

Neither one supplies economic growth.

> does that mean another factor is the main proponent for growth?

Increased productive capacity is the source of economic growth. Not the supply of currency.

Take a simple example.

Three people live on an island after a plane crash.

They fish, build huts, make tools. To facilitate exchange, they use paper money from the game Monopoly happened to survive among the wreckage.

One day a new box of Monopoly washes ashore, including a fresh supply of Monopoly money.

Their money supply has doubled.

Will they experience any economic growth? Clearly not.

The next day a power saw and generator wash ashore. They have new tools and increased productive capacity.

Will they experience any economic growth? Clearly they will.

Thank you very much for your response.

Furthering your point on neither deflation nor inflation driving economic growth but rather productivity increases, does that mean what the FED is doing through monetary policy zero sum?

I subscribe to a camp that believes that what the FED is doing through quantitative easing and zero percent interest rates, is actually harming the economy by sacrificing quality of life of persons without wealth (investments, property, assets) for gains for those that do (real estate bubble, stock market gains since 2008). Can this be true? Or am I looking at the situation too simplistically?

Regarding the topic at hand, do you believe that bitcoin's low cost of transmission and features such as escrow and consignment lend the commodity-currency true value (like gold's value being that you can wear it, use it for electrical equipment)? Or do you look at the protocol as having no intrinsic value (pure fiat)? -And do you think that that matters as a currency?

Many skeptics claim that a crypto currency backed by a mineral would be ideal, and that bitcoin's only value is in it's perceived worth. They also believe that this means it could be a big tulip party waiting to crash.

I'm not sure what to believe regarding bitcoin's future, as gold has had 4000+ years to earn it's place in the world. Thank you for your time.

> does that mean what the FED is doing through monetary policy zero sum?

It leads to malinvestment as you pointed out.

> Can this be true? Or am I looking at the situation too simplistically?

I agree. It's a wealth transfer.

> Or do you look at the protocol as having no intrinsic value (pure fiat)? And do you think that that matters as a currency?

I'm not a Bitcoin expert. Right now I see no value in it in the short term other than a speculative investment.

There is much political uncertainty surrounding it. It could go to zero in a day.

Like you say, gold has over 5000 years as a consistent store of value. Bitcoin is a few years old and wildly volatile.

Do I believe a crypto-currency with no real-world backing could thrive? Sure, someday.

Do I believe that crypto-currency will be Bitcoin? I have no clue.

You're missing the point. We all have to buy food today, but we have a choice on whether we use bitcoins or dollars to pay for it. If you believe that bitcoin will get more valuable with time, due to Bitcoin's deflationary design, it's always the rational choice to spend dollars rather than bitcoin.
I am well aware of "Gresham's law" that bad money drives out good.

I'm just referring to the idea of deflation in general and the fear mongering that happens around it.

I'm not talking about Bitcoin versus USD.

Well then maybe you should point that out in your initial comment.

I'm just referring to the idea of deflation in general and the fear mongering that happens around it.

You'll have to do a little better to support your claim that deflation can result in economic growth. One data point from a rather unique point in history isn't enough.

> Well then maybe you should point that out in your initial comment.

Okay I will next time!

> You'll have to do a little better to support your claim that deflation can result in economic growth. One data point from a rather unique point in history isn't enough.

This isn't my claim.

My claim is that economic growth comes from increased productive capacity and not from manipulation of the money supply (neither inflationary nor deflationary).

See my simple economic example elsewhere in the thread.

Your argument only holds if your time discounting factor is greater than the rate of deflation. In the case of Bitcoin this is clearly not the case since prices can double overnight, unless you're arguing that you're so adverse to waiting that you'd rather purchase something today than tomorrow at half price.
I'm just talking about deflation in general. Bitcoin is a new phenomenon but the 'fear of deflation' argument has been used by monetarists for decades.

Bitcoin is hardly viable as a unit of account at this point. It's a speculative investment at the moment.

> The argument goes that if people know that prices will fall, they will indefinitely delay all economic activity.

No, it doesn't. It goes if people know that the future purchasing power of currency will increase, they will shift more investment to currency itself and invest less in things like real estate improvements, businesses, etc. -- and that investments in the latter have a multiplier effect and whereas money invested in the currency itself does not, such that, ceteris paribus, shifting to deflationary currency would reduce the overall level of economic activity.

It is not that people would direct defer economic activity, and even less that they would defer all such activity.

> We've seen periods of significant economic growth coupled with falling prices.

And we've seen periods of stunning economic collapse tied to deflation. But individual examples without considering other contributing factors and underlying processes and incentives aren't particularly useful.

I am not an economist, but I thought that both Austrians and Keynsians agree that fiat currency with steady, moderate inflation will increase economic activity versus a steady deflationary currency.

The disagreement is whether or not artificially generating economic activity by inducing inflation is a good thing or a bad thing.

The Austrians think that the increased economic activity consists largely of malinvestments due to artificially cheap credit, which will cause a short-term boom, followed by a subsequent crash.

The Keynsian view is that you can ease out of the boom without a crash, and that the markets will take too long to equilibrate without such an artificial increase in monetary supply ("In the long term, we're all dead").

I am also not an economist, but I'd like to frame your Austrian/Keynesian comparison with another one:

Underinvestment (Austrian): There is less investment due to risk being less preferable to steady savings. Example: I won't risk 1 million dollars today on a risky investment if my 1 million dollars next year will be worth more.

Overinvestment (Keynesian): These is over investment due to inflation outpacing savings. People are forced to invest in risky ventures, as at least there is a chance you can earn money as opposed to losing money over time. Example: I risk my 1 million dollars today on a risky (subjective, I'm referring to -10% to 10% gains) investment and if not, will definitely lose 5 percent of that money.

I'd love to hear your thoughts on the matter. Personally, I see strengths in both styles of economic policy, but believe that in our current economical climate, we are overinvesting and through central planning, mis-investing by stimulating the top echelon of investors who simply buy property (real estate asset prices go up), businesses (mergers & acquisitions), and commodities that hold their value. Look at the rise in value of fine art over the last 6 years. These to me, are signs of a bubble.

Another argument from the Austrian school is that even if a theoretical impartial Keynsian could manage the economy better than the free-market, the reality is that such an impartial entity doesn't exist, and the more centralized the power over the economy is, the more prone it is to corruption.

That is to say the wealthy will ensure that the central banks make policy decisions that benefit them at the expense of others.

The 'why buy something today if it will be cheaper tomorrow?' was never very convincing to me. There are many markets, look for example at computer hardware, where delaying a couple months can get you huge savings. And yet people buy new hardware, all the time.
What would happen if bit coins were produced at a steady rate indefinitely? Maybe not linearly but at some predictable growth rate. The amount of bitcoins in circulation would always go up and therefore decrease the value of each in circulation?

Obviously I don't know much about economics but I can't see why this wouldn't work. Why does bitcoin have a hard limit on the total number of bitcoins produced?

  After some careful calculation, you determine that it will
  cost you 1 BTC to produce, market, and sell a single widget,
  and that it is only worth your effort if you can sell each
  widget for 2 BTC, a handsome 100% margin.
I stopped reading right here.

This is trying fit a deflationary currency into a debt/consumption driven economy. Who says the best way to drive the economy is by taking on debt to consume good and services? I would argue that debt counteracts a lot of the gains set by consumption.

The falling wages argument seems irrelevant...what's the difference between wages increasing 2% to keep up with 2% inflation and decreasing wages 2% to keep up with 2% deflation. Don't confuse numbers with value.

I would argue however that the RATE of deflation is important. 90% is brutal...2% not so bad. Theoretically the rate of deflation of bitcoin's should decrease as time goes on.

Even in a non-debt driven economy debt plays a useful role at a micro level in terms of financing productive investment, not just discretionary consumption. Deflation will increase the real value of debt, making it increasingly difficult to service the debt over time (since your wages would probably be falling), whereas inflation reduces the real value of debt over time.
I think the "deflation can't work" people are making the same mistake as the "interest can't work because one penny will eventually be worth as much as the weight of the earth in gold" crowd ("Joseph's Pfenning"). They interpolate incorrectly.

In the case of interest, some borrowers go bankrupt (which is fine, because the world needs risk taking). In the case of deflation, presumably at some point people will want to buy things. They can not hold on spending forever because they might starve.

In any case it seems obvious that the price of one Bitcoin can not go to infinity, because there is nothing of value "infinity" on earth. From that it follows that the deflationary dread scenario has to come to an end at some point, just like Joseph's penny can not accumulate interest long enough to be worth the earth in gold because all his lenders will go bankrupt before that.

Seems to me the problem pointed out only exists if you view the transactions without taking their larger context into account.

Take his "100 Widget @ 1BTC each to produce, sell them later at a different value of BTC." scenario, which he characterises as an 80% loss. Now consider where the widget maker would have got his initial 100BTC from, and what he'll do with the BTC he sold the widgets for. Using his numbers, lets say you sold 50lb of butter to get your initial 100BTC. Several months later, when you've sold all your widgets (for the deflated 0.2BTC price) and you've got 20BTC in your wallet, you convert that back into your original resources, and get 100lbs of butter at the new 0.2/lb rate. All of a sudden the exact same scenario now looks like a 100% profit (50lb of butter becomes 100lb) instead of an 80% loss (100BTC becomes 20BTC). Admittedly, hanging on to the original 100BTC would have allowed the widget maker to sit on his hands for a few months and then buy 500lbs of butter, but looking at just the BTC deflation without the outside context makes things look very much worse than they really are. And ultimately, it's butter (or opamps or widgets) that you need to eat/live and that have "real value" in some sense - those 100BTC could just as easily have turned out to be worthless at the end of the widget production run - and the widgets could still have been sold for USD or traded for butter. The guy with a private key to a magic number proclaiming "100 BTC" might have had _nothing_ Not a problem if you can afford the gamble - not such a great idea if you _need_ that butter to feed yoru family.

You're missing the point entirely. It's about opportunity costs.

If you try to use a deflationary currency for any economic activity then you get bitten by deflation, you end up losing money. The fact that the total revenue you get back is still worth the same (in butter or what-have-you) is irrelevant. You still had to buy equipment, you still had to pay people wages, and so forth in that currency to start with.

But if you had not invested that money to start with you'd be even wealthier.

The major point is that bitcoins or dollars aren't actually worth anything intrinsically. They have no value. Value exists in goods and services. With a deflationary currency people are discouraged from economic activity which produces more goods and services because it causes them to lose money.

I think I was making a _different_ point.

I think BTC is a perfectly fine transactional tool. Much like credit cards. I can buy and sell things with my credit card, but I can't eat positive or negative numbers on my bank statement - in one sense it's not "real" until I turn those numbers into something of "value", perhaps butter - perhaps some other abstraction of "value" that I trust, like dollars.

Dollars as an "asset" are reasonably safe. Using dollar assets for investment in other value-generating activity is fairly well understood. But ask anyone from Greece or Zimbabwe if they'd entrust their families future to their local fiat currency…

BTC as an "investment" or "asset" are quite different. There's _very_ much more reason to hold on to BTC rather than invest them in any activity that's going to return less than several hundred percent annualised returns (there's a _very_ good reason why Silkroad's major commodities were what they were). If I can expect to double the dollar value of my bitcoin holding just by waiting another few weeks, of course I'm not going to invest any of that into widget raw materials or manufacturing plants. But there is definitely a US property market style risk for people sitting on large number of BTC. The notional "value" keeps going up at a startling rate - but it's still a crap shoot - there's nothing _guaranteeing_ you'll get any value at all out of your BTC - it's even less "sure" then US residential property market or Credit Default Swaps or Collateralized Debt Obligations from a few years back. It's not impossible you could buy "$25kUDS worth of BTC" today, and find you've got _nothing_ next year, instead of $50k or $100k or $500k - there were _lots_ of investors and property speculators with expectations like that 5 or 10 years ago≥

Given that bitcoin only has notional value: if it's not used as a currency, with prices denominated in it, then what supports its value? If nothing does then you have the recipe for a speculative bubble, and crash, and little else.

At least gold can be made into pretty jewelry and electronics.

It's pretty much the same as post-fund-raising stock market "value". Snapchat is "worth" 4 billion dollars in exactly the same way as a bitcoin is worth $1000 - enough people _believe_ it's "worth" that much that you can buy and sell some form of notional ownership of them - at least in small amounts – based on that value. If everybody stops believing in bitcoin or Snapchat, that value will plummet and perhaps disappear. The government will try to prevent that happening to USD, but ask a Greek or Zimbabwe person how their fiat currency has gone as a "reliable store of wealth". So long as people keep believing in BTC it _might_ maintain a real value - it does provide some real-world convenience to some people, so it's not impossible that it'll maintain long-tern value I guess.

I can't help but think though, that there's way more people "talking it up" because they have enough BTC stashed that another order of magnitude increase in BTC conversion rates will have many of them jumping to exit with "fuck you" amounts of money - with the inevitable deflation as their BTC all hits the market in a big rush…

Hardly. Those companies make things. The provide services to people. That's real, concrete value.

Companies can be over valued, but certainly there is some value even in snapchat. There is zero non-notional value in bitcoin. It's just a currency. But if it's only used as an investment and not a currency then it's unlikely to retain value indefinitely.

Fiat currencies certainly have some similar problems, but because they are used heavily as currencies much of those problems are mitigated. Everyone around me is getting paid in dollars, everything at the store is denominated in dollars. Taxes are in dollars. Etc. Because of economic activities there is a tremendous amount of inertia to the value of the dollar. The only inertia inherent in bitcoin is the market valuation, and that is dependent on, effectively, a pyramid scheme. Once the value of bitcoin starts falling everyone will want to divest from it as quickly as possible, merely accelerating the collapse.

This is economics 101, we've seen countless speculative bubbles before, if you don't believe that speculation is a risk in the BTC market then you're just unaccountably naive.

If the BTC market started falling at the same rate it is going up right now, and persisted in doing so for 6 months what would you do with your BTCs?

There's deflation, and then there is DEFLATION! Five days ago Litecoins were selling for approximately $7/coin on BTC-e. As I am writing this, the price is over $36/coin. If you had bought $100 of Litecoins last Friday, that purchase may now be worth $514. There is almost nothing that you can spend Litecoins on -- with the exception of buying other cryptocurrencies. It reminds me of the height of the dot com bubble, except several times "worse."
I find many defenses of bitcoin hilarious.

A lot of people are pointing out how great it is that bitcoin increases in value over time. Except there are at least two problems with this. One, few people who say such things have any concept of economic theory. Two, nobody seems to care where that value comes from. Somehow they just think it comes from magic, or somehow it has no cost associated with it.

All in all it's precisely reminiscent of any and every speculative bubble throughout history. The market will always go up! up! up! Where does the increase in valuation come from? How is it possible for it to be sustained? Who cares?! We're gonna be rich!

Yeah, good luck with that.

(Edit: all of which is to say, if you want to fly in the face of conventional economic theory, go ahead, but bring some better arguments to the table than "well, it's just been going up the last few years!")

the deflation argument:

1) if value of A increases relative to B, people with A that want B will wait to trade for B

Make A money and B some good and you have the deflationary spiral argument. But notice that the structure of the argument is unchanged if we make B a good and A money. The sellers and buyers are symmetric - when you buy a good with money, you are selling the money for the good. If the deflationary spiral is correct, it is correct both ways, and if it is correct both ways, it isn't correct at all. Any temporary asymmetry in price movements run into time preference barriers that return it to a relative equilibrium.

If people are waiting to trade A, then there will be a shortage of A, which means (in a marketplace) that people trying to trade B for A will need to trade more B. The pressures are not symmetric just because the action is when we restrict our viewpoint to two participants.

What does this suggest about the argument?

> it will cost you 1 BTC to produce, market, and sell a single widget, and that it is only worth your effort if you can sell each widget for 2 BTC, a handsome 100% margin.

That's a 50% profit margin, not 100%.

profit margin = 1 - cost/revenue = 1 - 1/2 = 0.5
