"As more and more people started mining, the difficulty of finding new blocks has greatly increased to the point where the average time for a CPU to find a single block can be many years." [Bitcoin FAQ]
The big winners in Bitcoin are for-profit electric utilities and anybody who manages to trade a bitcoin for something of value. The losers are, well, anybody who trades anything of value for a bitcoin and anybody who subsidizes his electric company by running this compute-bound crap 24/7.
orcishgamer: I'm glad I'm not the only one who gets this. Bitcoin has inflation built in, the early adopters (and founders) have tons of Bitcoins for relatively no investment. You need a 200 dollar powerbill to mine any these days, and no, charging for expedited transactions does not make up for the imbalance. It's a scam, though not built like normal pyramid scams.
It's about as much of a "scam" as being early adopters of gold, back when it first became a popular measurement of wealth. Gold is harder to mine today than it was from the beginning, and the early adopters were probably well advised to store their gold for the future, since its value increased as more people started using it to facilitate trade.
Bitcoins (and the algorithm used to make them) are designed to mimic this property of precious metals.
AndrewC: Mining resolves those equations that handle the crypto process. In short, what you're doing when you're mining is verify the validity of transactions and coins, and this in turn grants you coins.
orcishgamer: Actually you're wrong, mining is trying to race to solve a a crypto problem to be awarded new Bitcoins by a central authority, that somehow Bitcoin users believe does not exist.
If there is a central authority responsible for the distribution of bitcoins then I'd like you to present it to me. Until you've demonstrated this, I'll continue to assume that Bitcoin creation is handled by the decentralized network.
The process of mining Bitcoins can best be compared to the process of mining a precious metal. Unlike fiat currencies, which are created, distributed and protected by a central authority such as the Federal Reserve, Bitcoins are "harvested" by individual "miners" that solve algorithms in order to generate Bitcoin "blocks". There can only ever be at most 21 million Bitcoins in circulation, most of which still haven't been mined. As demand for Bitcoins increases (if it does, which it has so far), the amount of Bitcoins in circulation should also increase due to increased mining. Due to the work involved in mining the coins, however, this should never result in hyperinflation, just like gold or silver doesn't hyperinflate.
In the end, the value of Bitcoins will be determined by market adoption by both producers and consumers. Due to the high publicity and larger user base Bitcoins have received in the last few months, I'd consider adoption of the currency by retailers a good business decision, since the Bitcoin network is starving for goods and services that can be bought directly with BTC. I'll certainly look into it if and when I start my own software company.
The issue of Bitcoins being "unreliable" is really irrelevant to the discussion. As long as there's an exchange service like Mt. Gox available to buy your Bitcoins for "real" currencies, I can't see why GoG, for instance, couldn't simply exchange all their Bitcoin income to Dollars if they so wish.
