Obviously this seem as a good time to be. However I think it is still to early. Do not be fooled we are in a bear market, and I believe we will be for the most of 2022 even 2023, so in my opinion I think you should wait, although I do not think BTC will go lower that 15k.
I have the same opinion, I DCA bitcoin regularly, but I am also more inclined to open a short position to the 15k level, as this decline should be gradual over two years
