This year the price of bitcoin has dropped for a long time, and don't know how long bitcoin will be like this. I think this is a year of challenge from bitcoin, those who are strong will stay here and the weak will leave, this will be an option to determine the future.
Bitcoins suffers so hard in 2018 that most of the people were thinking that this is the end of cryptocurrency overall. But I suppose that in 2019 we will bloom again and cryptocurrency will become more trusted as it was in 2017.
