Understanding Bitcoin takes some degree of experience, and thus time. Many people are discovering how the value-meaning exchange cognitive systems we call "money" actually work, by using Bitcoin. A fascinating example of this process is detailed on this article that was linked today from the top of Bitcoinwatch:
http://www.libertariannews.org/2011/06/06/libertarian-goldbugs-hating-on-bitcoin-free-market-money/to wit:
"I suspect that many libertarians who denounce Bitcoin as a legitimate currency system have purchased large quantities of gold and silver, and are looking to recoup some of their investment by having those metals make up the groundwork for a new monetary system. It would stand to reason that anyone who holds large amounts of precious metals would be opposed to any new currency system that is not based on those metals...."
Human beings use money systems as a "translator" between the inner world of subjective value and the outer world of physical experience. Bitcoin, despite its digital nature, is not different in this respect.
When the so-called "crash" happened, I, like many people, was a bit worried. Quickly I assessed my feelings and thoughts about Bitcoin:
a) Was I using it to accumulate value in a speculative manner vs. the dollar? (Answer: to some degree, yes)
b) Was I already "thinking in bitcoin," i.e, looking for spending opportunities for goods or services that were denominated specifically in bitcoin? (Answer: yes. Although in my case, these goods or services were related to the mining of bitcoins: PCI-E extenders, for instance. Still, I bought them in Bitcoin, not dollars.)
c) When I looked at my bitcoin holdings as the price dropped precipitously, did I see the entire holding as converted mentally to value equivalence in my national currency? NO. I sold some bitcoin at 23.84, guessing that the market would stay down long enough for me to buy more at a lower price, as well as take some cash out towards paying back some of my investment. I later bought back about 160% of the amount of bitcoin that I had sold, at 60% of the price. Today, of course, the market is back to 18<->20.
d) does Bitcoin have value for me as a intrinsic currency? YES. Increasingly I will look for opportunities to spend Bitcoins simply to use them in the emerging marketplace. Likewise a percentage of my holdings also will serve as a speculative investment vs. my national currency. BUT ONLY A FRACTION, probl. less than 40% overall.
I know that there are many of you who have much more experience than I in using this new system. But I have learned enough by now - both from mining and from playing small amounts in the Bitcoin market - to trust this system, which paradoxically, is based on the "no need to trust" due to the cryptosystem (see Bitcoin paper). Ironic, to me. But all money systems contain such feedback and circular logic. MONEY SYSTEMS ARE BUILT ON PARADOX.
The key is: do we all accept the paradox together?
