It's really amazing how bitcoin is growing too fast with just a short period of time. The phasing was really fast despite the FUDs and forks that has happened. I believe bitcoin will rise higher than today. I cant help but to get excited for the next year 2018. No one knows if there will be a great decline on the price. But I am waiting for that to buy bitcoin. And about the hacking of nicehash, i think it wont make a big impact since the bitcoins that has been hacked would still circulate.
