bitcoin will be much stronger. This has been proven many times in history. Bitcoin prices each year confirm a new record. And this year I believe the bitcoin will come back vigorously and raise new record prices compared to 2017.
Such a pump as in 2017 will not be accurate (at least in 2018). Then no one expected such a sharp jump in the up and so bitcoin was actively bought by those who are not very well versed in the market and then burned out. Now, even at 20% of the pump, no one will buy bitcoin so actively, because they have already learned the experience of 2017 and so willingly part with their funds no one will.
