After several days of narrow consolidation during Christmas and the weekend, Bitcoin's volatility space remains severely compressed. Over the weekend, a rebound rally occurred again, with a rapid surge in the early morning pushing the price from a low of 87,402 up to a high of 88,023. Ethereum followed suit, reaching 2,954. The short-term profit potential is quite considerable, and the current trend is largely consistent with previous ideas, with no significant deviation in direction.

From a technical perspective, the daily chart has recently been oscillating between the middle and lower bands. Each breakout ends with an upper shadow, indicating that while the bulls are attempting to push higher, their momentum is clearly weakening. The market is expected to continue oscillating and battling within a range, awaiting a second breakout signal. The four-hour chart shows gradually declining highs and slightly rising lows, with the triangular range further narrowing. There are no clear short-term directional signals. However, on the weekly chart, the price remains repeatedly consolidating in the bottom area without forming an effective upward reversal, so the overall bearish pattern remains unchanged.

In terms of trading strategy, focus mainly on the resistance levels within small-cycle high-level oscillation ranges as the primary reference for short positions. Simply put, as long as the price cannot effectively break through recent resistance, it is an ideal entry point for short positions.

Short-term outlook: Bitcoin faces resistance around 88,500, with the downside target at 86,000; Ethereum is under pressure near 2,980, with the downside target at 2,880.
