Realistically, I think a slow drift upwards is in the cards for 2017, and we might not get quick changes like we saw a few weeks ago. It'll go back and forth, but chances are a general upwards trend is the plan.
Worst case we get a repeat of 2013.
Situations similar to 2013 won't happen again. This year bitcoin popularity along with adoption and capital is expected to increase. This time I wish that bitcoin needs to give a good increase in price by the middle of the year, though we don't have any special events similar to bitcoin halving.
