After the major level pullback of BTC ends, it returns to the original downward trend. The minor level has newly developed selling pressure after consecutive declines, which is not favorable for short-term increases. Prepare for operations with a mindset of making moves after pullbacks.

Aggressive support at 83910~82710 (can enter during a slow decline, do not enter during a sharp decline)

Short-term support at 81920~80330 (if reached within the day, quick in and out; if reached after 3~5 days, it can be held for the medium term), second support at 78760~76260~74110 (1:1:2 can be placed, seize rebounds during sharp declines)

Short-term resistance at 87640~88410 (for monitoring reference, a selling pressure area formed after declines in the early morning, expected to play a role in slowing the rise), structural resistance lower bound at 89510~90144.

Note: The validity period for aggressive strategies is usually 2~8 hours, and short-term points are valid within 24 hours, while the second points are valid for 48~72 hours. The major level support and resistance that have not been reached previously are generally effective.
