Bitcoin went long at key levels yesterday

90700 once, 90600 in the evening
Profits are still good, but above the Fibonacci support level, and when breaking through the 15-minute long-short boundary again, entered a long position
Yesterday also formed a door, so there were two opportunities to go long
Currently, liquidity is too weak, but there was no breakthrough, and it also did not break below the 4-hour long-short boundary, indicating no selling pressure and possibly some support from buyers
As long as the 4-hour level does not break down, there is a chance for a rally, but once it breaks, immediately go short
