Analyst prediction is just a speculation and it's never guaranteed to happen, so many predictions that a bullrun at the end of 2018 will commence but it didn't. I think it's best to prevent listening to those so called experts and just let market do the thing then react accordingly.
That right, there is no need to think badly to see Bitcoin continue to fall this year but you should continue to think good things will come with the crypto world. Anything can happen for now.
to support thinking good for bitcoin I think bitcoin will not fall again because in 2020 there will be a halving day that will happen to bitcoin, whereas from some cases bitcoin halving days a few years ago it could generate price increases, so I'm sure by the end of 2019 Bitcoin is recovering and becoming more expensive than before.
