If I look this far, people make big improvements, as more and more people are familiar with bitcoin. Almost all of them are interested in joining bitcoin. Therefore, the bitcoin community is increasing. With the speed of the bitcoin community, the popularity achieved every day positively impacts on the bitcoin itself. As more and more people now have to convert paper bills into bitcoins, it will continue to raise the price of bitcoin constantly and I am sure by 2018 there will be more bitcoin members growing.
