$BTC Last night temporarily supported around 88000, the weekend rebound is not strong, there is a need for a continued pullback. After breaking below 88000, there is weak support at 87400-87125, and this short-term long position can be taken or not. It is better to enter long directly at the 12-hour Bollinger lower band 86666-86300. Then look at the support at 84600-83800.
