The ultimate pressure of Bitcoin is around 90000, to be precise, it's at two positions 88500/91000.
Given the current market liquidity tightening, I don't think Bitcoin can directly break through 91000 and return to the bull-bear boundary!
So I shorted at the current price of 88200, planning to add to the position if it rebounds to 91000, with a stop loss at 92000, and a first target below at around 85000.
