The fatal flaw with internet currency

Ever since the outbreak of the financial crisis in 2008, discontents have been searching for an alternative to the current international monetary system, with its reliance on the US dollar.

Some have fixed on the yuan as a substitute for the greenback. Yet, although China's leaders like the idea in principle, in practice they have been cautious about allowing greater international use of their currency.

In any case, to hard-core critics of the existing financial architecture, the yuan suffers from just the same disadvantages as the US dollar.

As they see it, the problem with conventional currencies, like the US dollar or the yuan, is that they are issued by governments. And with control of the printing presses, indebted governments, they argue, will never be able to resist the temptation to print as much money as it takes to pay off their debts, debasing their currencies and destroying the purchasing power of their citizens' savings.

This libertarian fringe longs for a currency independent of governments, whose supply cannot be debauched by central banks, and which trades outside the normal banking system.

Some believe gold is the answer. But gold can get stolen, which means it has to be stored in a secure vault. And that means governments in financial trouble can always seize their citizens' holdings, just as US president Franklin Roosevelt did in 1933. As a result, enthusiasts have identified another possible replacement for the US dollar: the Bitcoin.

Invented in 2009, Bitcoins are a digital currency designed to allow users to make internet payments at minimal cost.

The system is decentralised. Instead of transactions being cleared through a settlement system operated by a central bank which issues the currency, payments are validated by users running clever algorithms, and who are rewarded for their services with the creation of new Bitcoin units.

Bitcoins will never amount to anything more than a curiosity on the outer fringes of finance

But the best feature of Bitcoins, as far as financial libertarians are concerned, is that their supply is limited. The pace at which new units are created automatically declines over time, with the maximum possible number of Bitcoin units fixed at 21 million.

This limit means the currency cannot be debased. What's more, Bitcoin income is tax free, and Bitcoin savings are independent of banks, an advantage which prompted a surge of investor interest at the time of the Cypriot banking crisis earlier this year.

In mere weeks, the price of Bitcoins shot up more than tenfold to US$266, before dropping back to US$100 (see chart).

Despite the slump, believers remain convinced Bitcoins are the future of money.

Unfortunately, there is a fatal flaw with the whole concept. The very feature which most excites enthusiasts - the currency's limited supply - means Bitcoins will never amount to anything more than a minor curiosity on the outer fringes of finance.

With Bitcoins currently trading at US$100 each, their limited supply means that if they were to gain wider acceptance, their value would soar. And that would mean the value of goods and services priced in Bitcoins would have to fall - a lot.

As a monetary unit, the Bitcoin suffers from the same problem as gold. Its limited supply would make its widespread adoption massively deflationary. And deflation is one of the greatest economic evils there is. In a deflationary economy businesses have to sell ever greater quantities of goods and services to generate the same revenues and to service their existing debts.

But when prices are falling, consumers defer purchases, so making those sales becomes more and more difficult. In other words, deflation depresses demand and pushes up the real burden of debts. That removes the incentive to invest and crushes economic activity.

Alas, Bitcoins will never catch on. Nice try, must do better.

As with gold, prices don't need to be set in Bitcoin for it to be a good store of value.
Bitcoin offers several advantages over gold and national currencies. It can be used anonymously. It is flexible and fast. You don't need to use it as a store of value in order to use it as a medium of exchange. You definitely don't need to be a libertarian to appreciate that.

If each Bitcoin was worth $1 million USD, the current smallest unit of Bitcoin 0.00000001 would still only be worth one penny.
Bitcoin doesn't have to replace your inflationary debt money you love to be successful.
Also might be worth reading some of the material here: ****en.bitcoin.it/wiki/Myths

The irony is BitCoin is still valued based on the very currencies that BitCoin supporters want to do away with.
Plus, I don't foresee going to my local bakery to give him a string of 33 characters that he have to check for me to buy a loaf of bread.
How often do people (with the exception of bank note geeks and collectors) stop to look at the serial numbers of the bank notes that they give/receive when buying stuff and giving/receiving change? And these serial numbers are definitely shorter than 33 characters.

This is an unfortunate misconception. stateless said it right, this is solved in that bitcoin is infinitely divisible. It's already being discussed widely that people will start speaking in mBTC which is .001 bitcoin, making the current value about 10 cents a mBTC. There is values all along the way - currently down to .00000001 BTC but this is totally scalable in any direction.

HK_eh!
so is any fiat currency, USD, GBP, YEN, etc. pyramid scheme, the central bankers print as much as they like.
the only difference with Bitcoin is central bankers don't control the printing.
