Update on Btc analysis: The short-term price was knocked down after reaching the resistance line, with the lowest point dropping below 69,000, and then it bounced back. From a technical perspective, a head and shoulders bottom pattern was formed here, and the minor pullback has confirmed the low point of the right shoulder, so I've temporarily given up on shorting.

Currently, attention needs to be paid to the resistance line in the upper neck line range of 71,500-72,000. If it breaks through, the head and shoulders bottom pattern will be established, and the pullback high is expected to approach the previous high. Considering the formation of the head and shoulders bottom pattern, I plan to prepare for a pullback to go long, expecting to enter long positions in batches around 70,000-69,000, including both 1-hour and 4-hour levels which also show a head and shoulders bottom pattern. Therefore, the probability of a short-term pullback is relatively high, and for now, I will watch for a rebound trend.
