price goes up mid year and goes down end of year been since 2012 this beahvior but will rise more to 800 into 2017 so buy a bit before and expect a full year even for just 1 btc
I think the price will rise to more than $800 in the middle of 2016. There are several reasons for that. The first is the adoption of blockchain technology by conventional banks. They are working on the technology. They should have something to show by that time. The second is the halving of block rewards, that will reduce the pressure on the price with only 1800 bitcoins come to market every day instead of 3600 at present.
