Saying the price of bitcoin doesn't matter is a lie. There is a cost of acquiring bitcoins. Only a fool or a very very rich guy would think otherwise.
I agree with you. Price is a very important criterion. And for everyone who has several coins the price is very important. Everyone watches as bitcoin becomes more expensive or cheaper
People take decision of buying or selling their coins looking only at the price of bitcoins so price is really important factor when it comes to bitcoins and it is only the price of bitcoins that attracts people to start using it or invest money in it.
