If I answer you no then I'll be lying. Even though my hope is for us to see 1 btc equivalent to 1 btc some day with the price of fiat mean nothing to us, the current movement of the price still gives us the indication in how well accepted btc is and its demand. I do agree with your reasoning but until the I will still closely follow the btc price movement.
Yes its totally matters to us , because if the price of btc doesn't matter so why people are using it for investment .
