Perhaps only touch $ 9000 if positive information occurs in the coming time. The $ 20,000 price as of 2017 i do not believe will repeat because we need more time. Bitcoin still the most attractive although the market is bad.
We don't know that yet, from what I know Bitcoin price rally don't really have any limits and last year we really don't have that much good news to start off with a big price rally. What had happened back there is a lot of market participation happened which had more than doubled and triggered the biggest FOMO we have in Bitcoin's history. Now with a lot of people staying in our market participation we really don't know what will be its max growth (or if it will really reach that level) all we can do now is watch and ride the movement.
