2017 was already awesome, 700% increased is not but isn't it? I haven't seen any market that increases so much, 2017 is just the beginning and wait till 2018 has to offer. Maybe $15000 is possible and even more. I'm expecting a great year for bitcoin, specially if CME will start next year. And the popularity of bitcoin could double or even triple in 2018 so its hard to imagine what will be the price around first quarter, maybe we are in $15000 by  that time.
