I have no assumptions about this, as it is meaningless to assume. In 2019, there is a chance to become better only because 2018 was very bad (many assets lost 80% in value). This is the logic. Although many assets may lose this year, for example, 90%, in this case, 2019 will be even worse than 2018. But many are so tired of the long decline of the market that they refuse to accept this opportunity.
I agree with your opinion. I believe that the cryptocurrency market is promising in a long time. What will happen in 2019 is impossible to guess
