BeefEater: I would reply to all of you if it wasn't so clear that you're not willing to change your viewpoints. As is usual on the interwebz, you're not in the discussion to learn anything new, you're just here to throw mud at your opponents. Bravo.
wpegg: That train runs both ways. You can also learn something new, and change your viewpoint, but you also seem intent on keeping with the viewpoint you came in with.
What can I say, I don't like me or anyone else being called a moron for liking Bitcoins. Like I said, if people resort to mockery it clearly shows they don't have an open mind about the subject.
I was (and remain) a believer in scarce metals like gold and silver to secure wealth from the constant inflation of national currencies. As such, I was very skeptical to Bitcoin when I first heard about it, because it's not a "physical", tangible commodity. I hold no stakes in Bitcoins, since I only started reading about them a few days ago (I have plenty of free time). I've made no investments yet, except testing my luck generating bitcoins in a "mining pool" which clearly isn't worth it anymore (I got the equivalent of ~0.03$ by mining for 2 days).
The success of a currency depends 1. On its properties, and 2. On public acceptance. The first aspect facilitates the second, unless force is involved. It's well known that Dollars and other fiat currencies would be worthless if they didn't have a government enforcing them, because they lack the properties of ideal currencies like gold, the most important property being
scarcity.
There are only two ways to guarantee scarcity for a virtual commodity: Through responsible central production of the currency by a single company, or through decentralized "mining" activity that requires work to be done for Bitcoins to come into existence. The Bitcoin creator chose the latter approach, which I think is a stroke of genius on his part since it simulates the work needed to mine scarce metals.
Who cares if some people made more Bitcoins because they were earlier adopters? It's always the early adopters that rake in the cash, because they are the biggest risk takers. Bitcoins probably weren't worth the electricity they took to produce, even back when it was easy to produce them. They were essentially worthless compared to the dollar. The value raised as
adoption increased, and the miners were rewarded for their investment. This is in no way a scam, it's just basic economics.
There is clear demand for Bitcoins from several audiences who aren't interested in it just as an investment. As long as these people continue to use Bitcoins to facilitate trade, it will continue to have value on the market, and exchange services like Mt. Gox will continue to exist. As long as they exist, companies like GoG that (presumably) want to store their wealth in "real" currencies, will be able to do so while accepting payment with Bitcoins.
And no, gold isn't popular just because it's yellow and shiny, or for its industrial uses. Up until the last century, there wasn't much use for gold beyond decoration, but it was popular as a currency since long before that. The properties that make it popular are that it's easily identifiable and a scarce commodity. Bitcoins have both of these properties. In addition to that, it's cheaper to transfer than actual gold for long distances, which is an upside.
It seems to me that Bitcoins have all the properties that a successful physical currency should have, except in virtual form. It's basically got the "properties" aspect nailed down. Whether it becomes successful in the end depends entirely on popular opinion.
And no, I don't think Bitcoins are perfect. The downsides may be unforeseen technical details relating to security, and the total supply of bitcoins may not be sufficient if everyone starts using it (though it's divisible to 8 decimal places). Because destroyed Bitcoins never reappear, Bitcoins may become subject to unwanted deflation, which while increasing value of the currency may decrease its practicality for small payments. In the event that Bitcoins become popular and these flaws expose themselves, another virtual currency could be developed that irons out the flaws of the first. It's like any new technology.
Edit: Also, Bitcoins are (or used to be) in a bubble for the last few weeks due to increased investor speculation. Bitcoins are highly volatile at the moment because it's new and used by few people as of yet. It's received lots of publicity in the last month alone, which can account for the bubble it's been in. The exchange rates will stabilize with time.
