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.
This is where technical indicators would be significant and could really be that beneficial even though it wont really be giving out assurances that it could really go that way but we know that there's
really some probability as you had projected out basing with those tools or indicators which is far more better on using it rather than on having a pure guess or speculation which other people
been doing. We cant really spot the bottom but at least we had some hints and ideas on where it might be going in next days or weeks or months to come.
