Price matters a lot. Because if you make a polling of users getting into bitcoin, majority of them were into it just based on the increased pricing. So pricing is the one that makes the people into the bitcoin usage and the rest is upon their understanding about bitcoin.
yes you are right the price of bitcoin matters a lot because it is the high price of bitcoin that made the people into the use of bitcoin and also a lot of people are involve in bitcoin due to high price and this high price become very useful for the investors traders and bitcoin holders.
We will see the real price for Bitcoin only when they cease to manipulate the crypto currency market. I understand that large whales use their large amount of Bitcoin to regulate according to Bitcoin and thus influence the entire process. Of course Everyone has his own benefit and for that, but I think that we do not see the real cost of bitcoin to date.
