of course the price matters. it matters for the people who bought their coins. if the price is stable more people are willing to convert their savings into bitcoin.
Some people who had bought large volumes of bitcoin back in 2009 when prices were 10USD/1BTC are the real profit-makers. Imagine the profit they have made in 2016. Holding the coins is a passive income just because the prices are always bound to increase.
On the other hand daily trading is also useful as long as you keep eyes on the market and have some proper skills. All you need to do is buy at low price and then sell at high price, but make sure to get target prices since you never know how much really prices will fall or rise.
perhaps because of this, users always pay attention to the price of bitcoin bitcoin. events in 2009 until this year, making the price to be really important. now maybe people back to save bitcoin they have for a higher price. especially for those who do not sell their bitcoin bitcoin when the price reached its highest point
Yeaa we cannot avoid the fact that the price is the only thing make people interested in bitcoin.
Without the volatile price and the high price of bitcoin, i don't think people can find another reason to be interested.
It is always about the price no matter what , at least for now.
