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.
Yeah, but in 2016 bitcoin also has good increased started about $400 and be able reach until above $700 and then bitfinex got hacked. But, as we can see that bitcoin price could recover to $600 again, we just hope it will rise in the end of this year.
