Intrinsic value is alot more complex than it seems.

Many people attributed the skyrocketing price of silver as testimony to the declining value of the currency, etc. That's partially true, but the events of the last few weeks have established that about 25% of silver's valuation was linked to the ability to buy it on margin. Tighten the margin, and speculative demand vaporizes.

The difference between, say BitCoin and the Euro is that there isn't a mature market to establish the value of BitCoin. What there is a small amount of demand and a small number of people who control lots of BitCoin.
