According to the Fibonacci retracement line:
BTC has rebounded 50% at the 4-hour level and is now back to 38.2% (57,300). Looking at the support situation, it is still a weak rebound. BTC can take half of the profit if you follow orders in the short term.
The daily level rebounded for 2 days and reached 23.6%. There is a need to continue to rebound. Near the 38.2% (60,400) line, there is a small level of volatility. Look at the 4-hour 57,300 support at 16:00, and then look at the rebound strength.
