Felix Salmon worries about it:
If millions of people started using bitcoins on a regular basis, the soaring value of bitcoins would actually be disastrous. You’ve heard of hyperinflation: this would be hyperdeflation. Take a gold bar valued at $600,000. At $60 per bitcoin, the value of that bar is 10,000 BTC. But then assume that bitcoins rise in value to $600 apiece, and then to $6,000, and then to $60,000 — as would have to happen if the fixed number of bitcoins was being used to store hundreds of billions of dollars in value. Then the value of the gold bar would plunge, in bitcoin terms — to 1,000 BTC and then 100 BTC and finally just 10 BTC. The same thing would happen to all other goods and services in the world, including your own salary. Everything would be constantly going down in price, if you thought in bitcoin terms.
Inflation is bad, but deflation is worse. The reason is that in a deflationary environment, no one spends money — because whatever you want to buy is sure to become cheaper in a few days or weeks. People hoard their cash, and spend it only begrudgingly, on absolute necessities. And they certainly don’t spend it on hiring people — no matter how productive their employees might be, they’d still be better off just holding on to that money and not paying anybody anything.
The result is an economy which would simply grind to a halt, with massive unemployment and almost no economic activity.
