I used price pattern behavior from previous halvings to make a future diagram projection. I calculated an estimated low price of $8000 - 20K, high price of $100 - 120k (possibly higher depending on actual low) and target of 10-15k or less by the end of the year.
Past corrections were ~75% from ATH with bearish behavior for about 12 - 20 months following the bullish phase. I estimated the accumulation phase to start about 12 months prior to the halving (based on past data). I connected the swing highs and lows to zone in to where the bearish phase will end and when the accumulation phase will begin in anticipation for the next halving.
