There have been endless discussions on this, the only thing it coms to is the fact, that are you in it for the technology or do you have money invested. If you are a person using it for sending money to another place, and only buy it at the point of the use, then it doesn't matter. But if you happen to store it for long term, then obviously it matters as you will essentially be losing money on it.
Yes it actually matters especially to those users and bounty hunters because their income is based on the price of the bitcoin. I can say that their income is directly propotional to the price of bitcoin.
