i think it is in the eye of the beholder...the one who seeks easy and fast profit, the price does of course matter, for the one who tries to make an investment of the litle they have to hopefuly gain a couple bucks more it also does. But, if your prespective is that, this coin is the future of economics and worldtrade, that we are witnesing the beginning of a new base of economy and trade, then the current price is of no importance. So, in practicality, it does matter, 'cause people try to profit from it selling and buy, investing and mining. On the theoretical and philosofical point of view, it is just smth to study, maybe to get prepeared for.
True, without these prices, these guys will not even make a comment here, it's all about money and will always will be.
Some people, including me viewed bitcoin as a form of investment and will be holding it like a treasure. The price have got up and will got up more in the next few months, I dont how long are we going to make this run but the money behind is what drove those investors, without this value, BTC will be just a name.
