For me of course the price matters. It matters because the price of the bitcoin not stable, if the price of the bitcoin is rising stably more people will be willing to invest or convert their money to bitcoin to make huge profit.
It is due to decentralization, as long as using decentralized system then the price will continue to matter and fluctuate so as to make us must be ready with all things, but this is the advantage because many used as the future investment because expect the price to go up.
