The present price rally of bitcoin might be the start of something big in the coming years after the bitcoin halving that will happen on the second half of 2020. I believe that this year's bullrun will be mild but it can still match or surpass its previous all-time high last 2017 before the year end. But several big corrections might still hit the top coins before that final push for this year and this corrections might pump some altcoins for several days.
