Very difficult to spot the bottom but spotting a range that BTC could hit , that can be done with a little research on the other bull runs so personally , I do think BTC will keep going doing during the summer period and it might do down all year. How much ? hard to say but I don't see Bitcoin price going under 8-9k$.
I also see that some believe that bitcoin hit the bottom 2 days ago but only time will tell and next coming weeks and months.
