I think this year 2016 will also be remembered as a bad year for bitcoin due to recent bitfinex hack. In which 1,00,000+ bitcoin were stolen which is comparatively big and due to which market get dumped so hard.
2016 is not a bad year for bitcoin, neither is a good year for bitcoin because if you compare the price of btc before july 2016 and today's price, then you can pretty much say that btc has already made a good growth in this year. but then the bitifinex hack has stopped the growth for a while but it didnot either cause a big disaster in the price of btc. we are still too high compared to the prices before july. so we have to be happy with the current market price because atleast it is not beyond the last year's price. just my 2 cents!
