2017 was the remarkable year in the industry and it will take a lot for another year  to get to that standard.  So no,  I don't think 2019 will be all that remarkable.  I am certain though that a few projects will hit the roof : MFChain for example, is one I believe has that ability.  There will also be coins that are not worth a farthing, and alot of them too.  The coming year calls for adequate and extensive understanding of any project,  we may see scam projects worse than we ever have.
