It really makes me laugh when I read on the forum that people really believe in the new Bitcoin ATH at the end of this year.

Perhaps they really don't understand what bear market means, or hasn't seen it before. But for us who have been here at least in 2017, have seen the worst in 2018-2020, this is just a repeat, so mostly likely this year is just the start of the bear market and might continue till 2023 or early 2024 or prior to the halving, approximately in May.
So yeah, we can't do anything at every month's end so just be prepared for the worst this quarter, at the end of the month. I still remember 2018 December though, some pump before Christmas and New Year, but that's it.
