It seems to me that the cryptocurrency market will begin to recover in mid-2019. It would be very cool, because everyone is waiting for this.
I wouldn't bet everything on early 2019. We are already almost half in the second month and still BTC is rising up/dropping down (being manipulated) around the price of 3.500$.
If we see another rise as the 2017, it will propably be after the halving, but be a more slowly and steady. So, my bet is on early 2021.
