Yes I know it's an altcoin app but you can hold and send BTC as easy as a text message to your contacts, what other app does that?

https://play.google.com/store/apps/details?id=org.getgemsmessenger.app&hl=en

Wiper Messenger on the App Store does that for the iPhone. Bitcoin only.

The argument for deflation has always been that the holders of cash should be able to claim a fixed fraction of economic output even if that output grows.

With a fixed number of Bitcoins each coin represents 1/21millionths of the whole economy and as the economy grows the holder of 1 Bitcoin still has claim to 1/21millionths of the larger economy. If a home is dropping in value (priced in bitcoin) then this just means it represents a smaller and smaller fraction of the total economy. So maybe it should fall in price in terms of Bitcoin. Same Bitcoin balance buys more.

Some think that's wrong.

This other side of the argument is that a holder of 1 Bitcoin should be able to buy a fixed amount of goods. A crate of apples for example. If the economy grows by 10% and the fraction of value of the total economy that the crate of apples represents falls 10% then so be it. He is still able to buy the crate with his Bitcoin. The economy as a whole requires more Bitcoin over time to account for the extra 10% for this stability in purchasing power to happen.

If one wants his own purchasing power to rise with the economy he should loan his money (and take risk) under an agreement that accounts for inflation, positive or negative. He should not expect to hoard his cash under a mattress and get more goods for them in the future.

In the end we can all agree that instability in Inflation/Deflation is bad. However, absolute inflation vs. zero inflation or deflation, even if stable, is really a choice between a fixed value for your unit of money in the future vs. a fixed fraction of economic output for your money as the economy grows.

Which is a HUGE part of the economy!!!


It is a huge parasite on the economy, yes.  Their true added value is essentially zilch, and they can appropriate them a lot of production, through seigniorage that goes with monetary inflation.


Umm,  production requires credit if you are big business.  Without finance production would massively slow down.

In a mildly deflationary enviroment cost of borrowing is too expensive. People wont afford to buy big ticket things like houses or cars if they had to pay cash.

Yes. You need loans to move the money to the people with the opportunities, the ideas, the drive, the vision. Only in very rare cases do these people have money of their own.

Now with loans the important factor is the stability of the trend. Inflation or deflation that is constant for many years can be accounted for in loan agreements. However, shocks causing inflation or deflation to change can be disruptive, even ruining these people.

And they all go down the same % point, so this relative decline makes you at status quo, and you didnt lost anything after all.

=========

And the same for the consumer, yes his wages go down, but the prices of the stuff around him also goes down, so its only an illusion that you lose money , when infact you didnt gain nor loose anything.

Where is the story of sticky wages in this? The one main reason for loss of real output and increase in unemployment during an economic shock and it doesn't show up anywhere in your narrative.

It's never "the same % point" and salaries never drop as fast as they need to, not for the currently employed, so they lose their jobs.

Again, this deflation is caused by a lacking of demand, which printing more money will just make it worse long term wise. All new money is added in a form of debt, and raise the debt repayment cost later on. That large amount of debt repayment will decrease everyone but bank's spending power, but what they spend for? To buy more bonds (loan them out to trap more people in)

Creating more money is the way to increase demand. What is your solution to "lacking of demand"?
Business debt produces more prosperity than the value of the debt. Businesses pay off debt and yet show profits all the time. Otherwise businesses would not borrow. Also, the reason central banks buy debt to increase the money supply is so they can have assets they can sell later to reduce the money supply when economic conditions change.

...
There is only one exit for this endless slavery, that is give up using fiat money as a transaction medium, but few realizes this

No. Slavery isn't what fiat is producing. There may be better ideas around on how to regulate the current money supply other than using a central bank, but your ideas are not among them.

So, the claim of deflation's negative impact is just based on a stubbornly hold belief that currency is a benchmark of value. In fact the whole modern monetary theory is constructed on this blind belief

By this argument inflation is irrelevant since inflation's "negative impact is just based on a stubbornly held belief that currency is a benchmark of value".

By this argument all the "benefits" of deflation are an illusion.

The observable fact is that the adjustment from mild inflation to mild deflation is painful. People lose jobs because both employees and employers do not reduce salaries fast enough and loans are paid off in fixed amounts and end up sucking more resources than expected to pay off and therefore reducing investment.

The ironic thing is you are right that, theoretically, the value of money does not matter and is quite arbitrary. It's the unforeseen changes in the rate of change of money value that causes problems. Steady is best. You can write contracts (loans and employment contracts) that take a steady %2 inflation or a %2 deflation into account.

So, given that we were at %2 inflation, why not just leave it there since contracts already take that into account? Why call for unneeded pain by calling for switching to a currency with deflation when the benefits are an illusion?

If you worked for a living and your wages were in Bitcoin and Bitcoin deflated (i.e. its value went up) say from $200 to $400, you would be fired. If you claim you'd agree to a wage drop then you're really saying your salary is not valued in Bitcoin. It's valued in bananas or something and only paid in the equivalent Bitcoin.

You clearly don't understand how inflation and deflation works, you're forgetting that because the prices will lower due to the currency becoming more valuable that it will make costs cheaper for employers as well when it comes to materials and other expenses.

Stop trying to exclude one or the other to suit your arguments and agenda.

Sorry, but some costs for employers will not fall. His debts will remain the same and so will your salary.

Wow the neo-keynesian trolls have certainly gone to town here already, I should point out there are those who believe it's a bad thing because of falling prices, what they fail to grasp, is that's only a bad thing for people who rely on high prices in order to make money, such as speculators and people holding various assets, who these neo-keynesian economists are on the side of.

For the rest of us like you and me, deflation is absolutely fantastic, it makes everything easier to afford and allows you to build up savings, you aren't being forced to work twice as hard for half as much and it protects you against market manipulation of the money supply which is what causes these price swings neo-keynesian economists are so afraid of. Another thing to bear in mind of course is that for some baffling reason particularly on this forum the words inflation/deflation have been twisted in their definition to suit the neo-keynesian viewpoint, when I talk about inflation/deflation I am talking about the currency supply, when you print currency and increase the supply that's inflation, when you keep things the same or in fact reduce the amount of currency supply in circulation that's deflation and it causes the exchange rate of that currency to rise against others which is what's happening with Bitcoin and the dollar.

Yes, you're actually recognising that the idea of falling prices being a bad thing is a load of shit, I am building my investments right now and the rising price of Bitcoin is helping me a lot and is a perfect example of why deflation is a good thing, the idea that inflation helps people is a joke because while it may make a short term rise happen as is what's happening in the stock markets right now everything is going to collapse and be a catastrophe. The central banks are advocating the printing of money to keep things going, it isn't out of any benign purpose but it is to keep all these prices we're seeing artificially high, eventually it is all going to collapse in on itself, the only question is how long they'll keep things going, all inflation is, is a very sophisticated form of market manipulation.

Don't fall into the trap of arguing in a debate with people who use made up definitions for words or alternate realities in order to help them win, inflation/deflation is to do with currency supply, it isn't anything to do with prices, prices falling and rising are a result of inflation and deflation they aren't actually the process itself, people who argue using these terms are trying to sweep the issue of currency supply under the rug.

If you worked for a living and your wages were in Bitcoin and Bitcoin deflated (i.e. its value went up) say from $200 to $400, you would be fired. If you claim you'd agree to a wage drop then you're really saying your salary is not valued in Bitcoin. It's valued in bananas or something and only paid in the equivalent Bitcoin.

Deflation is bad.

The adjustment period is bad because wages are sticky and won't fall fast enough without a lot of unemployment pain (and forever lost production). But, more important, loans are quoted in fixed currency amounts so current loans become a much larger burden on families and companies if incomes are falling.

Investment will fall. People will be fired. Consumption will fall. And we all will be on a lower standard of living path.

(and don't give me the "people will adjust to falling wages" argument. That's just a recipe for a lot of needless pain and ignores the fact that people have existing loans.)
13  Economy / Economics / Re: Will negative interest rate be a boon to Bitcoin? on: March 04, 2015, 03:33:44 PM
With negative interest rate, nobody would want to keep their money in vaults and having to pay the bank just to do a favor for them. That's a logical thinking. With that in mind, assets would definitely be a better bet. You somehow won't find a person who converts all his/her fiat to bitcoin but you will most probably find the investment portfolio spread around, like holding property, stocks, trust fund, gold, and of course, bitcoin will be one of them.

One point to add. Bitcoin is the most liquid of these assets. There is a demand for liquidity. If you want to spend money at a moments notice but don't want to haul around cash and don't want to pay the banks %1 for the privilege of a checking account, then you may turn to Bitcoin. This will cause a slow rise in the value, further reinforcing the trend.

I donít know how interesting you find this, but interest rates have, in fact, gone negative. This is happening all around the world. $1.9 trillion dollars of European debt now carries negative nominal yields, and the overnight interest rate in Swiss franc is around -1 percent annually.

Just to be clear, this is for fiat cash deposited at banks in Switzerland. See Evan Soltas;

http://esoltas.blogspot.com/2015/03/whats-actual-lower-bound.html?m=1

To paraphrase: Would investors, in response to persistently negative nominal interest rates on deposits, keep currency in bank vaults? Or would investors start bidding up the price of any asset that can function as a store of value and try to find ways to make their holdings function more like liquid deposits?

My take is that some of them will turn to Bitcoin. Highly liquid and a good store of value.

Still reading through this and so far it's very interesting but I wanted to make one comment. The paper should make clear up front that your use of the term "forge" is related to mining a block and not related to creating an illegal block.  You mean forge as in create not forgery.

17  Bitcoin / Development & Technical Discussion / Re: Child key derivation function on: November 11, 2014, 09:06:40 PM
Ok, so that follows my primary key hash concat logic that i striked out in OP (only BIP-32 calls it index, or sequence here), but then I need to store that index/sequence next to my child key... also I need to make sure the index/sequence is used only once too! hm, was looking for something cleaner.

Thx!

Depending on how many child keys you want you could search for child keys where the index is encoded in the bits of the child key. No need to store the index with the child key.

Most child keys would not have this property, but those that do are obviously children of the master key. You extract the index from the child key and re-derive the child key from the master key.

For example you could start generating child keys with index i starting at 1 and going up. The first few bits of the hash of the child key could be compared to i. If it matches, this is a usable child key.

Unfortunately, you'd be lucky to find a key with this property. You can increase the probability of finding a child key if you allow yourself more child key candidates per index. You could hash n times for example and if the first few bits of any of those hashes matches i you have a usable child key. Of course you have to check possibly all n candidate indexes to show that the child is derived from the master.

Probably too complicated for your application, but then, I don't know your application.

19  Economy / Economics / Re: Defiatize the unit of value on: November 08, 2014, 03:26:41 AM
There is nothing called "total fiat money", only two types of money: base money and checkbook money. Banks usually add them together and call it money supply, but this is to confuse normal people

You may not call checkbook money "money", but it's 90% of what most people and industry needs for commerce. Some countries are exploring eliminating paper money altogether. Base money will then just be numbers in checkbooks between the fed and the banks.  That will certainly "confuse" normal people.

I'm not saying base money isn't important. It keeps the banks honest. In practice they never have to hand out more than a small fraction of their liabilities in base money. But they do have to produce it on demand hence they need to keep their reputations intact so they can borrow some when they need it.  This makes the correspondence between checkbook money and base money very tight.

My comments on the desirability of being able to borrow fiat (base or checkbook) still hold. My comments on the opinion that fiat (base or checkbook) is backed by loan contracts representing promises to labor also still hold. Banks will shun a bank that has ruined its own credit by not balancing its liabilities (checkbook accounts) with assets (loan contracts and the associated income).

Base money, of course, can be printed as needed by the fed. They print the right amount to target inflation at under 2%. That's the "if it's well managed" part of my comments. As far as I can tell, the fed seems to be pretty conservative in this regard.

An intersting alternative setup is to get rid of the fed and allow banks to issue their own paper money. See the literature on free banking for how that works. The idea is that if a bank abuses its power to print it is punished by the market when their paper bills are not accepted. The owners will have a market incentive to be responsible.
20  Economy / Economics / Re: Defiatize the unit of value on: November 07, 2014, 06:56:29 PM
Commercial banks does not create money, I mean base money, not some check book numbers in their database. When you ask for a loan, if commercial bank does not have base money, they can not give you a loan, that's a liquidity problem. Otherwise there will never be any bank failure, they could just loan to each other and create trillions of dollars

I'm afraid that's not right.

http://www.bankofengland.co.uk/publications/Documents/quarterlybulletin/2014/qb14q1prereleasemoneycreation.pdf

Commercial banks do create money. It may not be base money but base money is only a small fraction of total fiat money. They create a loan on their books and balance it with an asset which is the contract you sign for a loan, not any base money they may or may not have. Base money is only used for cash withdrawals, a very small value relative to their normal volume. If they run short they're allowed to run to the fed and borrow some.

They don't over borrow from the fed because they have to pay interest. They can't just have base cash sitting in their vaults if they have to pay interest on it.

Base money is small part of the total fiat money we use.
