> I'm pointing out the obvious. X bitcoins could be "worth" 5 cents or 500,000 in a matter of hours. So could your US Dollars. A fiat currency only has value as long as other people are willing to accept it as payment for various goods and services. That willingness is based on the belief that they, in turn, will be able to exchange the currency for other goods and services at a later time. The same principle applies to bitcoins. But a cryptographic currency like bitcoin has advantages that USDs don't. For example that massive amounts of bitcoins can't just be whipped up "out of thin air" like paper money can.
