We are going back to sub 7,000 as we speak. Possibly a bear market for 2 years like last time.
That would be sweet but I doubt it will happen. And 2 years is way to much. in 2013 were 2 spikes April and November and bear trend only last a year. 2014. "015 was already growth. slow but steady.
Personally I would love to see that Bitcoin price falls sub 5k and hangs there till mid 2018 but there is not that much chances for that.
