This expectations for Bitcoin to suddenly rise in 2019 sounds similar to me like expectations that Bitcoin price will reach 20000$ again at the end of this year.
I also believe that at some point in the next year the price will recover but it's very hard to tell when this exactly will happen and in want range. What I want to say is that people shouldn't expect too much in too short period of time. By that time try not to accumulate loss that is not necessary.
