BTC/USD - Short

Analysis shows historically that the market can retrace anything up to 80-100% of the move.
The previous bull run in Dec 2017 retraced approx. 88%.
Chart pattern shows a head and shoulders, which can indicate reversal.
Fibonacci from the start of this bull market to the high here could see a likely reversal to around the $10-15k mark for Bitcoin.
I have estimated by Feb/March 2022.
