Yes I think it's matter, because if the value of bitcoin was nothing, nobody would be interested by BTC, so of course his value is interesting. More his value is big more people who have bitcoins will be happy.
The higher price will attract more investors.
In general, the investors must involve the future of bitcoin. It would be much more effective when you buy bitcoin at a low price and expect tremendous growth in the future.
Well, if this will go on and on then this price would still be lower and if I were them I would really buy now. This only works for those who have a higher capital in their wallets. Better do it now than regret later. Like what happened to those who didn't bought bitcoin at the $300 mark. So price does really matter.
I really envy those that had the opportunity to buy bitcoin do more for nothing. Over the years, people are quite well raised their bitcoin and even increased on investment. Therefore, we will be more profitable to buy today, because the later can not succeed because of a light purse.
