This is very long bearish market, in 1 year the price of Bitcoin and others crypto did not going up to the highest level again. Can be the situation of crypto market right now just like in 2014-2015 , that mean for beginning of this year the market will side away and in the end of this year will touch again to the top price.
If following a similar pattern to 2014/15 it will take longer to reach the previous ATH. It was approaching 3 years before there was a new ATH. Based on that we won't hit 20k again until the end of 2020 or beginning of 2021. Of course history is not always followed exactly but if you overlay the price movement from that period to now there are a lot of similarities.
