I think our posts are talking past eachother as I did note the weakening currency in Cyprus and the increased acceptance of bitcoins for exchange in my response. Both of which will drive up demand for bitcoins and thus legitimately move the price, due to supply being fairly constant and predictable.
When I say "fundamentals" I am using the financial form of the word, as in the method of valuation that contrasts to "technical" analysis by trying to examine what actually comprises the price of something rather than just looking for patterns in how it behaves. A good discussion of the "fundamentals" of a normal currency can be found here (most of which don't pertain to bitcoin, but just try to think analagously): http://www.investopedia.com/articles/trading/04/031704.asp
I think you may also want to look into the "functions of money". As I was describing in my post, money doesn't serve just one purpose and while bitcoin is terrible at some of these, such as "unit of account", which all of: "predict your profits, give forecasts to investors, make long-term plans" fall under. On the other hand it actually functions fairly well as a means of exchange due to the fact that as prices fluctuate so can the value of the currency, something that physical currencies have a harder time doing. It isn't perfect and long term deals may require hedging, but as you allude to, there are ways to deal with this.

Hopefully this clarifies some of my points.
