What makes you so confident that a bull run is due this year? More hopium is definitely not what these people need.
I honestly think that it's more likely that 2019 will be quite boring overall, and if we do happen to see an increase of some sort, it won't be anything like a bull run. On top of that, due to clowns such as Tom Lee people have given up on perma bull type of predictions, and that's actually a good thing. It's super deceiving to promise people golden mountains while the market is a pile of rubbish in the short to mid term.
well the real question is whether you think bitcoin has stopped growing or being adopted.
if yes then you can conclude that there will be no more rises this year and we will continue seeing price going sideways or even drop more.
but if you think it is still growing and the adoption is happening then you can't say there is no rise this year. we have already had the drop which purged the market from that "hopium" dudes and all traces of the bubble and then some. so there is no other option left but to rise after this accumulation phase ended. and this phase can't take much longer.
