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.
Really ? Even with bitfitnex hack, the price of bitcoin back to normal again. For me, 2016 is really a good year for bitcoin, because we have the halving and it's make the price of bitcoin increase so high.
